> Reality in a lot of european cities is fundamentally different to most of the US.
I am not sure about which european city you are in. Here in Germany, there are more cars than people. Infact, there is so much parking shortage that, people walk 10 minutes away to park their cars, because the streets are already full.
Also, I don't know anyone going to store daily, most people shop en-mass over the weekend, mostly Saturday afternoon. Only people I see regularly on the malls near me are just retired oma/opa but they also shop like every 4-5 days.
That being said, while at least in the city I am in, has the most connected and excellent public transport, somehow I have to take a reverse de-tour by bus on my way to work, because bus routes are not often straight forward and there are only specific limited routes I can take, unless I can find a place near some U/S-bahn station(immensely difficult these days due to housing crisis).
If I had a car, I could reduce my daily commute to work by 2.5h, but then again, I don't have strict on-site requirements, so it doesn't matter.
