> Why would I even bother "owning" a car? What the more reasonable approach is time-sharing of multiple vehicles, like Uber. A huge problem remains though : how do you avoid having dirty/smelly/broken cars all the time when everybody is sharing cars ? People are usually way more cautious with there own stuff than with others'. The city bike-sharing systems around the world usually chose «indestructible» bikes to deal with this problem, but as a result you get a really heavy and uncomfortable bike and I don't think you could do this for cars anyway: no matter how robust is your car, spilled drinks or food on the seats are still a pain … This kind of system definitely needs a way to avoid the tragedy of the commons. Elinor Ostrom[1] showed that there are mechanisms to regulate this efficiently, but you need to actively deploy them and it's better not be an afterthought. If you do nothing and let people be toxic human beings, you'll end up with shared cars in worst shape than public transport (because in public transport you have a kind of social pressure that limits the bad behaviors) [1]: https://en.wikipedia.org/wiki/Elinor_Ostrom https://en.wikipedia.org/wiki/Elinor_Ostrom
