why won't people own cars? just because the car is driverless it doesn't change my need to regularly commute to work, or go to the store for groceries. it really doesn't change my usage pattern for a car a whole lot. it may change where the car will be parked when i am not using it.
people say it will make taxis cheaper...wouldn't that be comparable to renting a car today? you can rent cars now without a driver attached to it and last i checked it is still cheaper for me to own a car than to rent one. and the advantage of owning it means it is always available to me. if you always rent your car and make an unscheduled trip, you run the risk of having no cars available when you want one. even if you schedule your trip in advance you risk that the rental business could already be out of cars during the time slot that you need one. ever been bumped from a flight or hotel that has been overbooked? the companies running these will want the minimum number of cars to maximize their profits, they will want to overbook them with the assumption that a certain percent will cancel their ride at the last minute, because a car sitting idle is costing them money and not making them any profit. so what if that means 1 customer is going to be late for work that day?
renting cars will have to be a lot cheaper than owning before people give up ownership, especially if they use it nearly every day like they do now.
