This is a common carbrain argument
“I already pay the gas tax”
The problem is that it’s false.
In a recent study, researchers Stefan Gössling, Jessica Kees, and Todd Litman calculated the social costs of driving. They found that the social cost is about 30-40% higher than what car owners are actually paying

That cost is paid by non-drivers.


Yeah, also if road transport cost the actual price, more goods would be transported by rail and water, which is much better for the environment.
“We can’t afford rails, large infrastructure bla.bla.” Ah… Okay … but how then can we afford to replace the current roads every 5 years? It’s like everyone just take roads from granted because it’s a socialized cost.
