In Europe, yes. In switzerland, nope.
Track racing in switzerland is forbidden since quite a few years. They wanted to revoke the law about two years ago, but it didn't pass.
The nearest track for me is the "cirquit du laquais" in france, which is about a five hours drive from where i live. I'll go there someday when i find the time and money... was good fun in the MX-5 i had once.
How is the oil consumption of the S2k on the race track by the way?
