> in Manhattan, they are likely to be closer, but I'd guess that impact is more per time (stuck in traffic) than per mile

I don’t want to gamble on whether I’ll hail a taxi in time to make the train. And if I’ve spent a few minutes hailing such that it’s questionable if I’ll make the train, I’ll just gun for the airport.

> I am not convinced that they are better for the environment (i.e. emissions) than private vehicle ownership

If you can get people to not own a car, ridesharing wins hands over feet. In most of America, ridesharing just decreases private miles driven. There, the environmental impact is more mixed.

> prioritizing ride hailing vehicles over mass transit (i.e. buses) on public roads will disincentivize mass transit on said roads

I think anything that makes mass transit more accessible, or which pays its bills, is good. Because the default in most of the country isn’t busses. It’s private cars. If we get self-driving cars while busses are still on a legacy model, those systems will be shut down.
