This gets repeated a lot, but is unpersuasive. How much money should a transit system lose? $20 per trip? $40 per trip? There might be mass transit systems that make sense (e.g buses), but most mass transit in the US is terrible quality and a terrible value. One argument is that it's a jobs program for the disadvantaged, but even there we could find a lot of things more useful than moving around empty seats most of the day.

Roads are used and essential to every single person whether they use a car or not. Every single product you consume was transported over roads.

Drivers are the problem, not roads. Drivers kill, maim, pollute, and disturb the peace in ways AVs do not.
