is it? i dont see the relevant other studies, and my initial assumptions would be that the median subway user is lower income than the median car driver in NYC, so transfering funds from car drivers to subway improvements would be progressive.

However NYC's transit is notoriously bad at spending, so not sure it would achive that. Which studies linked in this thread are you refering to? I cant see them.

Regressive taxes aren't bad inherently bad. Regressive spending is bad.

In this case, you have a regressive tax with a huge positive side effect due to taxing an externality. If the funds are also spread into progressive services it can be a net positive for all income brackets.

TIL that word.

I wish as a society we'd use this form of taxation more, and widely applied taxes less. In theory insurance is supposed to have the actuarial people who figure it out and properly price the choices in, but it's also surprising how crude they can be-- lumping very distinct situations as "the same". eg aggressive drivers are only penalized after they hurt someone, like the phrase "no harm no foul" (until there is harm). It'd be better if telemetry was collected and penalized in realtime.
