The 'eSetta' by Tony Weichselbraun is a car that would be used for a car sharing system in urban areas. Inspired by the BMW Isetta, this tiny car is not only able to squeeze through small alleyways, but able to do so with style.
The car system would be much like a bike sharing program. One would pay a fee to rent the car, then drive to their destination where they would drop it off. Another benefit of these mini cars is that they are electrically charged at the stations and do not require gasoline to run.
Currently more and more bike-sharing programs are popping up around North America. This would be the first smart car sharing program if the idea continues to develop.
