I have to agree with you. Even on closed race course you are taking a risk, but that risk is Greatly reduced by the fact that it is being done in a controlled environment. Therefore making it a bit safer. It really is dumb to go flying 133mph down a public road regardless of the time of day or congestion. Not to say that I havn't done it. I have turned towards AutoX and Closed Circuit Courses for pushing the Boxster past legal freeway speed zones.

Also, back to your comment "I've tried, unsuccessfully, to break the rear end loose by going 65 ............"

I am assuming you have PSM turned on when you tried this? It is fairly easy to get the back out with PSM turned off. I would not suggest trying at speed of 65 mph. I keep it off for lower speed autocross.
