1. Carsharing is not the same thing as ride sharing. Carsharing (basically short term car rental paid by the hour/km) is an option anywhere. My girlfriend and I have used this widely in our nature adventures in Europe.

2. I am talking about possibilities of how we could reform our system and thinking, not the real life situation. Nonetheless, a taxi (ride sharing) is still a viable option in large parts of the world and the US.

3. Your attitude is unnecessarily hostile so I will shut this conversation down. Thank you for your time.

An alternative in this case is carsharing or taxis. Car ownership is a big issue, for every carsharing car you can get rid of up to 10 vehicles.
