Car Sharing: Overview and Zoning
1. Introduction
The sharing economy is growing at a very fast rate and transportation is no exception.
Industries and sectors have been newly created in the past two decades, with rapid iteration and
acceleration in the near future. Self-driving cars, micro-transit (micro-mobility) and the
Hyperloop, among others, are on the horizon. It’s important to be proactive in the creation of and
participation in these emerging technologies. With the intent of furthering discussions about how
Cambridge can effectively regulate and embrace new or expanding methods of car sharing, this
memo explores car sharing issues, how it is affecting the world, and how communities are
reacting to this innovation in personally owned vehicle transit.
2. What Is Car Sharing and How Does It Work?
Car sharing is a term used to describe the relatively new industry of car rental in which a
member rents a shared vehicle, typically for fairly short periods of time and distances. Car
sharing may also be distinguished by:
• Mitigated environmental impacts
• Contribution to a consumer multi-modal transportation network
• High-level use of technology
2
• Membership participation (includes gas, insurance, and limited mileage)
• Dispersed vehicle locations, as opposed to a hub
• Self-service 24/7/365 availability
Car Share Operator (CSO) Categories
• Business-to-consumer (B2C)- For-profit and non-profit companies own a fleet of
vehicles and rent them to members.
• Business-to-business (B2B)- Companies sell or rent their technology to businesses and
municipalities to turn private fleets into private car share.
• Peer-to-peer (P2P)- Individual car owners rent their personal vehicles to members.
CSO Business Models
• Round-trip (traditional car share)- Reservations are made in advance and require the
same pick-up and drop-off location (in a dedicated parking space in a lot, garage, or on-
street), and a start and end time.
o Use cases: grocery store runs, shopping, doctor’s appointments, meetings, and
day/weekend trips.
• One-way (station-based)- Reservations are made “on-demand” and allow for separate
pick-up and drop-off locations (in a dedicated parking space in a lot, garage, or on-street)
with an end time not required.
o Use cases: commuting to work, nightlife events with intent to taxi home safely,
bridging transportation gaps, last-mile transportation.
• Floating (flexible)- Reservations are made “on-demand” and are picked up wherever
they’re available, typically on streets and in open lots, and dropped off in any legal
parking space.
o Use cases: commuting to work, nightlife events with intent to taxi home safely,
bridging transportation gaps, last-mile transportation.
Operations
Most CSO’s define their footprint based on a number of factors including member base,
existing transportation market, and population and demographic information. Strong partnerships
are established to obtain parking with parking management companies, public transportation
authorities, universities, property management companies, and municipalities.

3. What Are the Organizations?
• Zipcar- Considered the world’s leading car share company and founded here in
Cambridge, Zipcar jump started the American car share revolution. Owned by Avis
Budget Group, they operate B2C round-trip/one-way models and B2C fleet share tech.
• Enterprise CarShare- Operates B2C in over a dozen U.S. markets, Enterprise’s car share
branch offers round-trip reservations for members.
• Maven- Owned by General Motors, recently pushed into over a dozen U.S. markets with
B2C round-trip reservations.
• Car2Go- Owned by Daimler AG and considered the leader in the B2C flexible model,
Car2Go brought a new type of car share offering to people looking for flexible pick-up
and drop-off locations and times.
• GetAround- Operating a similar model to Airbnb, GetAround is a P2P car share company
that allows car owners to rent out their personal vehicles to a network of members.
• Turo- Formerly RelayRides, Turo is the other major P2P car share company that connects
car owners to a network of renters.

4. Why Is It Important?
Car sharing provides many
benefits. Individuals are optioned with
a car ownership alternative and can
enjoy a care-free transportation option,
allowing one not to worry about
maintenance, car payments, insurance,
parking, and expenses. Car owners
that need or prefer to have a car may
opt to downsize their personal car(s),
as car share can provide secondary or
supplemental vehicles like vans for
moving, trucks for hauling, and SUVs
for larger passenger or load capacity.
Cities enjoy reduced traffic and
congestion, reduced wear and tear on
roads, increased urban mobility flow,
a tighter transportation network, more
available parking spaces, and cleaner
air. The environment is benefited as
car sharing reduces the number of
vehicles on the road, encourages
walking, biking, and public
transportation, and typically uses
newer and more environmentally-
friendly vehicles in their fleets.
Many estimates claim that car
sharing takes 5 to 15 personally owned
vehicles off the road, weighted toward
the latter, providing residents and
visitors with more parking.
Additionally, cars sit unused by their
owners around 95% of the time.1 This
presents another opportunity as the car
share footprint grows, because parking
spaces can become flexible when not
being used for car “storage”. New
technology allows CSO’s to rent out
car share spaces during the time that

vehicles are out on a reservation or away for maintenance/repair. With less vehicles, more
reliance on healthy and efficient commuting options, and a reduction in stress on city
infrastructure, public spaces (parks, bike lanes, sidewalks) can be used more equitably and
consciously.
The Future
A report has
forecasted that the U.S. will
spend $2.8 trillion on traffic
between 2013 and 2030,
which includes wasted time,
fuel, and the value of carbon
emissions.2 The importance of
proactive solution-oriented
steps must be seriously
considered by all local and
global decision-makers. A
synergy of multimodal
transportation options is
essential to the future of
urban and suburban mobility.
This synergy, as seen in
Figure 3, provides
overlapping and
complimentary options that
cover nearly every trip type.
Communities that adopt and
encourage this model
provide travelers with a
holistic, well-rounded
transportation network.
Current patterns and
future projections also show
that the transportation
industry is becoming more
diverse and at a faster pace.
Different models are being
created and segmented and
sub-segmented, as seen in
Figure 4.

5. Zoning Review and a Look at Other Communities
Cambridge
Zoning regulations are outlined in the Cambridge Zoning Ordinance Articles 6.21 and
6.24, and “allow the limited use of parking spaces for Carsharing as a means to provide mobility
options…thereby promoting City goals by increasing mobility, reducing reliance on automobile
ownership and use, and lessening the total demand for parking.”3
The language allows for station-based types of car sharing (round-trip and one-way) with
dedicated parking spaces, but appears to exclude the floating model. Companies like Car2Go
only operate the floating model and require unrestricted, on-street parking spaces. These
companies cannot lawfully conform, excluding their participation in Cambridge’s car share
network.
Similarly, peer-to-peer car sharing companies such as Turo or GetAround are, arguably,
business operations that cannot be run in residential districts. Therefore, car owners living in
residential districts cannot legally offer their private cars for rent through these platforms.
Boston
In February 2015, Boston initiated a Requests for Proposals (RFP) for a pilot program,
DriveBoston. The RFP called for two programs. The first program made available 40 dedicated
public parking spaces, both on-street and in municipal lots, per each CSO. The second provided
150 floating permits provided to CSO’s that operated a station-free floating model. The goals
were outlined to:4
• Reduce personally owned vehicles by targeting high car/low mileage areas
• Multiply the number of mobility options, fill transit gaps, provide flexibility in mode
choice, and alleviate congestion
• Increase car sharing visibility
• Connect and support “Main Street Districts”
Boston received responses from, and signed contracts with Zipcar and Enterprise
CarShare, but failed to formalize an agreement with Car2Go, the biggest “floating” offeror.
Car2Go has been looking to join the Boston market for years, but said the pilot offering was not
ambitious enough to deliver a viable service. The pilot moved forward with Zipcar and
Enterprise CarShare with 80 dedicated parking spaces, 49 in municipal lots and 31 on-street. The
pilot has been extended an additional year due to positive results and feedback:5
• Car share vehicles were driven seven times more than personally owned vehicles
• The average number of unique users per vehicle was 23, as opposed to two for a
personally owned vehicle
• Low-income neighborhoods saw the biggest demand and highest utilization rates

New York City, San Francisco, Seattle, Washington D.C., Hoboken NJ
Similar to Boston, these cities have pioneered car share pilots in similar fashion. The
common threads are access to dedicated on-street spaces and requirements for underserved
neighborhoods. New York City Council supported car share legislation, signed in 2017, to
establish an on-street car share pilot program.6
Minneapolis–Saint Paul
The Twin Cities lost one of their CSO’s due to high taxes. Car rental taxes total around
22%, justified by the fact that most rentals are made by business travelers, tourists, and other out-
of-towners.7 Car sharing is just the opposite, competing with car owners, not rental companies,
and are almost entirely local. Legislation was introduced in 2017, now in committee, to exempt
CSO’s from rental taxes and fees.8
California, Oregon, Washington
Governor Arnold Schwarzenegger signed new legislation in 2010 allowing residents to
share their personally owned cars in vehicle sharing pools without risk of losing their car
insurance (insurance companies previously did not cover a customer who shared their car in
exchange for money). California was the first in the nation to pass such legislation.9 Oregon
followed shortly after in 2011, and Washington in 2012.10 This facilitates individuals’
participation in the P2P car share economy.
6. Recommendations
Given Cambridge’s desire to minimize personal car ownership and use, it makes sense to
allow people to rent their personally owned vehicles through either B2C or P2P car sharing
companies. Because a vehicle’s safety is assured by already required state inspections and
because insurance is assigned to the car and required for a car to be registered in Massachusetts,
the City would be put in the position of guaranteeing vehicle safety for car sharing as it is for
home sharing. Further, unlike home sharing programs, renting of personal cars does not deplete
an important local resource such as housing. It would be important, however, to ensure that
people were not building rental fleets for operation out of residential districts. Because greater
ease of car sharing would be a net benefit for the City, reducing the need for car ownership by
residents, and because there is no need for City oversight beyond traditional zoning enforcement,
there would be no need for a permit or fee process to be associated with this program.
Accordingly, the City Council should amend the zoning ordinance to allow residents of
Cambridge who have registered their car in Cambridge to offer one car to the general public via
a car sharing platform. A possible zoning amendment would read as such:
9
4.27
Peer-to-Peer Car Sharing. Any passenger vehicle registered in Cambridge may be rented
by its owner(s) to the general public via an internet-based car sharing platform regardless of the
zoning district in which that vehicle is garaged or regularly parked.
4.27.1 Only one car per residential unit may be rented in this fashion.
