There are a lot of reasons that wouldn’t fly in the US:

• too tiny compared to the behemoths around. I’d be afraid
• doesn’t say speed but a lot of “city” cars have city speed limits: most people use high speed roads at least some of the time
• as average new car prices pass $50k, maybe people are less likely to have multiple cars than in the past

When I was married, I did always have a small cheap commuter car, like a Civic, and ensure my ex had the big car that’s also More comfortable on road trips. But I’m no longer married so can’t justify multiple cars. My one car does need to serve the occasional road trip, so I’m more comfortable with my current 300+ mile range.

But there continue to be more full sized pickups on the road and those are what I notice with worse and worse driving. I don’t even think I’d feel safe in my civic anymore, much less something smaller
