Anecdotal evidence: I moved to Switzerland after uni and was sold on the idea that everyone there is super green and on bikes all day. Hard truth on the ground was that all the locals were driving luxury German cars and only students, expats, thrifty youths and the poor(for Swiss standards) were on trains/bikes. Everyone I know with a solid income only commutes by car.
Still, public transport in most European cities is good enough that we can live without cars and I'm thankful for that.
