The thing is, a transit trip's true cost is also around $20 in SF and Seattle. It's just that perverse incentives hide it from users.

Waymo taxis deserve the same level of subsidies. It won't be happening any time soon because it'll be a death knell for transit, and will leave thousands of city employees without work.

This isn’t true, unless you’re willing to consider the subsidies that cars get when it comes to putting in and maintaining roads and doing urban planning around half the city being car surfaces.
