Thank you.
That is a huge problem. The solution is not to make it miserable to own your car; the solution is to make it wonderful to use a shared vehicle.
There's a natural aversion to the sense of losing your car. I have a car, and I think from your question you have a car. There is a loss. You feel like there might be a loss of something. We're averse to that kind of loss. In order to have someone change something, the thing that they're going to change to has to be almost twice as good as the thing they're leaving. That's the challenge.
To make the activity of using a vehicle and not owning attractive is a much larger challenge than the actual technology challenge of making a vehicle run by itself. Your question is so far unanswered. When you hear people say that no one is going to need to own a car, that's true rationally, but it's not true behaviourally and economically. From a behavioural economics perspective, everything that you're saying is true. Many people prefer to keep their car, and that's a huge problem.
I wish I had the answer. If I had the answer, I would be very wealthy.
Here's what's worse. Right now in Canada, fewer than 10% of all trips are taken in a non-family vehicle. If we get 75% of all trips in a non-owned vehicle 30 years from now, the whole world population of cars will still be the same as now, because our demand for trips will increase, and our wealth increases. That's one of the reasons we demand more trips. A small change of moving from 8% to 18% won't make any difference at all. Our congestion problems are far bigger than a few people shifting to robotaxis. It's a very big problem.
Thank you for that question.
