If you’re talking gas tax in the US, I’d say that’s laughable. Using eia.gov[1] as a reference, the prices are half of what we have in the EU. We’ve observed a steady increase in the prices (mostly due to taxes). But it didn’t have the effect, people just deal with the higher price and carry on. There’s even more cars than there used to be. And the average living standard in the east/SE EU is lower of that in the US.

When I was in Göteborg, Sweden, I saw this system where the toll increases based on the time, and it’s highest (~30 SEK = ~3€) in the rush hour. There was no price in the off hours. Maybe if it costs more to drive in the rush hour, one might think about not doing it or finding someone else to split the cost.

To rely on the “tax system” to take care of the congestion/traffic pollution problem, we’d have to bump the taxes and tolls by 10x to see any effect. EV is a step in the right direction, but only by a small amount. We need incentive to drive less, something that forces everyone to think before they drive. And by everyone I have in mind the person who is driving and also the person who is making them drive to the office to have their physical presence to do the same work they can do from anywhere. Make it more expensive for a company to have car riders and make them count commute as part of the workday. I believe remote work is a part of the solution to this and making it more expensive to get everyone to the HQ every day might make more managers reconsider if it’s necessary.

The linked article addresses how gas taxes are nowhere near good enough to solve the congestion problem, and especially not when more cars go EV.

This is already the case, and has been so for a little while.
