Run for whichever office I would need to hold to veto such legislation. I could solicit campaign contributions from vehicle manufacturers, oil companies, and automotive enthusiasts.

I would love an electric daily driver, but only the top model Teslas (which I can’t even dream of affording) have enough range for me, and even those don’t have any charging stations where I need them. Central Canada, things are *very* far apart.
So because even a politician can understand that, it won’t happen here until BEVs are truly ready to take over. At which time I’d be perfectly okay with it. Although I’d much prefer bigger pollution problems to be dealt with first, like ocean freighters which are kind of horrifying polluters and could easily be vastly improved.

Norway has been really good at making cars their enemies. Toll roads into cities are about to be adjusted to demand 27+$ per entry during rush hour. The toll ring in Bergen has been raised to 5.50$ per entry at peak times, which has reduced traffic considerably. In cities, that all might make sense. When I still lived there, I was biking 100-200km a week on average, depending on the season, and I’d occasionally take a damp and disgusting bus, too.
But…it doesn’t make much sense to me outside of cities. Yada yada, electric car ranges will improve and personal freedom will descend from heaven in the form of golden unicorns. Yet the energy density of batteries vs gasoline is still ridiculously different. All the cars on the road right now should be allowed to be used up without too punitive taxes. And what about really old cars and industrial heritage? Tracks only? There is too much unsure about this idea. We certainly don’t want to move out of our tiny paradise.
Another issue here is that Norwegian politicians are very attention craving and, occasionally, narrow minded. Big announcements and decisions are very popular. Next year, the country is supposed to switch from FM radio to DAB/DAB+, with the former being turned off. The problem is that DAB is already outdated. Why not rather install wifi along all roads? Or create radios that work on cell phone coverage – which is mandated to cover 95% or so of all households and thus a bit patchy on roads, but still much better than DAB coverage? Bleh.

The DFW DART has been in service 20 years now… and in those 20 years I have never ridden DART.
So what was the question?

Since, generally, the cities that enact rules like this have fantastic infrastructure for alternative transportation methods, I suppose I’d bike more or take the train.

I’d be just fine. I live downtown and rarely need my car – though when I do need a car it’s pretty essential. But for ninety percent of my needs I can walk, take transit, ride a bike, hail a cab, etc. Owning a car in a city is mainly an expensive hassle. AAA estimates the average cost of car ownership in the US at nearly ten grand a year – with all expenses and depreciation figured in. That could by a lot of transit passes or cab rides.
But, there are a number of issues sort of being jammed together here. A lot of the car bans are due to poor air quality (public health) and wanting to reduce carbon dioxide production (mitigate global warming).
Car free zones and entry restrictions tend to be more about managing congestion. That means that the area is generally dense and thriving. Limiting car access allows more people to move more rapidly on foot, bike and transit, than could if there were more single occupancy vehicles. And there are other quality of life aspects to not being immersed in gridlock all day long, including fewer accidents and injuries.

Get a place out in the mountains or country for my nephews and me to keep some sports cars.

There’s always the East Oakland strategy: ride ATVs and unregistered dirt bikes on public roads anyway. There are a few folks that do this and can be regularly found out past Fruitvale on International Blvd.
Ok, in reality, I’m for congestion bans on cars in city centers with good transit infrastructure. I’d rather take a train into town and not deal with dense traffic and parking. Right now, I BART to work on days where I go into the office.
I am going to be annoyed if I’m ever required to give up riding and driving liquid fueled, internal combustion engine powered vehicles.
