I'm from around Ghent in Belgium and study in Ghent and last year the city introduced a plan where no cars except for taxis and some public transport is allowed inside of the city centre. It's absolutely awesome because Ghent is a student city and you can get anywhere in Ghent using the bike but you can also get anywhere by car by parking nearby in an underground parking lot and walking the rest of the way. But it has made it so much safer and easier for cyclists (and people on foot!) to just get around.

Antwerp also recently introduced a measure where only cars with a low amount of "exhaust gases" (can't really find the proper name as of writing this) are allowed in the city centre. I haven't been there since, but it's also something I truly admire going into the future.

I visited San Francisco last year and it was a true nightmare to get around in Mountain View by bike. I have never felt more unsafe on a bike in my entire life to be honest. I am driving on a bike without a biking lane next to cars that are going close to 100km/h. It's truly insane. Visiting other cities in the US as well have been awful from a cyclist's point of view compared to most of the European cities and cities from the Netherlands are amazing as well (something you don't hear very often from a Belgian).

So all in all, please just ban the car in most places in the city imo or do something like Antwerp that drives (pun intended) people towards electric cars faster.
