I use cars more like I use a hotel. Inconsistently on demand when PT doesn’t cover the route I need.

If I bought and sold a house every time I needed somewhere to stay on holiday, renting would be massively cheaper.

I’ve already done the math and uber occasionally is cheaper than owning a car. Self driving electric will be even cheaper.

how are you going to compare cars with no fixed location premium with housing? also utilization is totally different - cars sit ~95% of the time, housing can be nearly round the clock if you work at home. transportation is more like a utility/commodity whereas there are so many personal factors for where to live.
