They use to be (along with Lyft). But it's been a very long time since that was clearly true.
In reality I think you can get better experiences than a taxi with a rideshare service (which they really haven't been for a very long time), but it's very hit or miss.
So less consistently bad as a taxi service... but far from consistently good.
Without a physical human operating the camera, at the site, yes, it should not be allowed.
This is actually the distinction in many EU countries, i.e. it’s allowed to record a movie if the operator is present, but doing the same thing remotely requires permission from a special authority/agency (that’s not in cahoots with the police).
