Random data point: There were 342 cars registered per 1000 citizens in Berlin in 2014 [0]. Same in other (large) cities I have lived in in Europe.
Typically, using the public transport in Berlin will be much quicker than taking the car.

In Helsinki, less than half of households have cars. In many areas of central Helsinki, more than 60% are carless. I'd be surprised if car ownership was significantly more popular in other European cities. If there's good public transit and the city is walkable, a car is a waste of money for most people.
