That would help, but wouldn't do much for the mountains of people in cars on the weekend... going to stores they could easily walk to.
Personal driving needs to be one of those things that you might do a few times a month, when necessary, to get to a destination further than 25 km away.
The only vehicles you should regularly see on roads are delivery, emergency services, transport trucks, and maintenance vehicles.
Anything else can be handled by public transportation, micromobility, walking, bikes, zoom calls, etc.
Yes, it's not easy for everyone to do that, which is why government should step the hell up and subsidize and incentivize the crap out of every mode of transportation that isn't a car. Give away free e-bikes to every family if you need to, just get people out of cars!
