I tend to think owning a overly-powerful car (which includes basically all German turbo diesels) is more likely to encourage you to drive fast.

I'm not a great driver... no serious accidents on four wheels in 20 years of motoring, but plenty of very near misses and I've messed myself up on two wheels a few times.

I'm definitely a slower, more careful driver since I got a Prius. It's the kind of car that gives you a few moments to think about why you just put the pedal down before it does anything.

If I drove an S3 or a Tesla P I'd be just another one of those otherwise conscientious idiots driving too fast.
