As a percentage Switzerland and particularly lausanne and the 'swiss riviera' must be among the highest in the world, I've seen a ferrari, maserati, lamborghini and porsche at one traffic stop before and passing (or being passed by) 5-10 porsches along a 15min strip of that highway is not uncommon.

Of course there are over 50 private (read 1-10m+ to walk though the door) banks with offices in lausanne, a city of 200,000 people.
