Examples of this pattern in action:

The North American CarSharing Organization
Car sharing is a revolution in personal transportation — mobility for the 21st century. "Get online" with a car sharing network and you'll get convenient access to a fleet of vehicles (cars, vans, trucks) in your neighbourhood and across the city — and pay only when you use them. Reserve the vehicle that best suits your needs, and use it for a few hours — or a week. And when you feel like it, grab a taxi, take the train, walk, ride a bike or take the bus. If you drive less than 12,000 km (7,500 miles) a year and you don't need a car for work every day, car sharing will likely save you money, give you greater mobility — and actually reduce pollution.

The Bicycle Transportation Alliance was founded in November of 1990 in response to the US appetite for oil and the pending Gulf War. Our out-of-balance reliance on the automobile has gobbled up petrolem resources, mucked up our air, caused innumerable health problems and carnage, isolated neighborhoods and neighbors, created suburban sprawl, choked our roadways-and this time had taken us to war.

The members of the BTA recognize the bicycle as the most efficient and least-cost transportation mode. A way to lead us out of energy depletion and dependence. A way to accommodate the expected influx of population on our transportation system. We believe that the bicycle should be a safe and convenient transportation choice for Oregonians. And we work to that end.
