This reminds me of when a friend became a cop. One day I saw him or I thought I saw him from far away but I couldn’t tell him that I wasn’t sure it was him because I couldn’t recognise him because of my myopia and, since I sometimes drive without my glasses on - what if one day he caught me?
Despite all the bs you’ll read here, Europeans also want bigger cars. For me the proof is that poor people car brands like Dacia no longer sell sedans.
I think the reason you don’t see many big cars is that we are generally so poor that we can’t afford what we would like to buy. At least where I live… Also our streets are old and narrow which makes it impractical.
