Yes, and I think that's the problem. The infrastructure is actually a cost for Uber. It's better to have less infrastructure. I have sometimes the feeling the infrastructure team at Uber is trying to build the tower of Babel to touch the heavens or something rather than considering that the end goal is giving people rides and not building more infrastructure.

I think people should recognise that the taxi market has an advantage. It's a distributed system and a market. Taxis organise themselves.

If you're going to replace an entire market with a centrally planned system and a giant electricity and compute eating machine then you better have something to show for it in terms of efficiency.
