Great for uber is still limited by traffic and is a lot more expensive than great transit which doesn't get stuck in traffic, and thus is much cheaper than uber for better service.

Bad service is much worse on transit though.

The hard part of Uber style driverless EVs being great is having extra roads to handle the extra traffic not actually building the self driving bits.

People in NYC don’t just save money using the metro vs a Taxi they save time.

NYC is the one US city where trains almost make sense, but there are a ton of downsides related to cost, safety, etc. I'd love to see all those dedicated right-of-ways put to more efficient use with self-driving vehicles.

NYC has out of control costs. Look to Vancouver canada for a very different picture.
