@jbruce - So, what I'm gathering here is that you are admitting to racing on a public highway at speeds of over 100mph? If so, you are a public bloody menace and do not deserve to own a driving licence let alone a Model S. Your stupid, juvenile antics will cause an accident one day, bring Tesla into disrepute, and probably kill someone (not to mention negatively affect my Tesla shares).
There was a similar discussion on the Norwegian EV forum, after someone let slip that they were certain the top speed of the Model S was unchanged with FW 5.9. (There is no speed limit above 62.5 mph on any public road in Norway. And most are 50 mph.)
Legally, it's of course a very simple issue, but morally, it's a bit more complex. It is a fact that it is possible to achive speeds over 100 mph in a Model S with a substantial degree of safety. One example is on a race track, but there is no reason to think that that is the only circumstance where it is possible.
Some factors:
1. The Model S can achieve high speeds in a short distance, due to it's superb acceleration. In fact, one can go from 0 mph to 110 mph and back down to 0 mph in about 550 meters/0.34 miles. With such a small distance needed, one can actually have a fairly good overview of the entire situation.
2. Speed limits are usually closer to worst-case speed limits than best-case speed limits. So, while it can be dangerous to go over the speed limit in bad conditions (windy, ice, rain, etc), it can be safe to go more than the speed limit when conditions are better.
3. Driving abilities vary from person to person. What's "fast" for a 65 yo person who's barely driven before isn't necessarily "fast" for a 30 yo race car driver.
