Here in my city, even though the public transport is already considered among the best of Europe, and you only hear praise about how well connected everything is... (so you wouldn't expect any radical improvements any time soon) on a Sunday I still take ~16 minutes to cover 14 km (8.7 miles) by car to meet my partner, while the same distance by p.t. is <checks on Google Maps...> 1h20m. So yeah, no thanks.
I picked 2 points at random in Helsinki, separated by 14 km, and Gmaps says it's 24 mins by car or 48 mins by public transport, so while it's already double, it feels much more reasonable.
Still there is the problem of reducing ability to have a lifestyle that implies many movements. E.g. after visiting my partner I went another 25 km (15.5 miles) to have dinner with my family. On the way back to my home I stopped by a utility store to buy some stuff. All those trips combined would have meant too many hours spent on a subway or bus (checked it: 2h50m and that's giving up on the shopping stop), but combined by car were a mere 1h15m.
I get the people who say "I don't have any use for a car, my city is phenomenal", but I also think a subset of those people might simply have assumed (deliberately or not) the limitations it implies, and would possibly achieve more things in their day to day if transporting themselves was a quicker process.
Points of view and different opinions are welcome :)
