I really want to be in the business of writing the software that plans these things. The possibilities are crazy. Predicting where to have cars based on overall traffic flows, having cars ready for individuals who always leave at the same time. Think, a car is 30 seconds away every time you follow your routine. That's faster than getting into and starting your own car! Especially if you have a parking garage.

The raving reviews you'd get the first times people order a car and are told instantly "your car is already waiting right outside your door" would be rather interesting.
Get in, and your favorite radio station or music is playing.
And for colder climates: Your car is already pre-heated. I remember too many winter mornings during winter in Norway when even ensuring our car would actually start in the morning was an annoyance (even with a garage, space heaters in the garage or motor heaters is sometimes necessary).
