Maybe the Pace in Wisconsin is a little slower than the rest of the country, or it could be that you don't get out much, or drive in the mountains. I'm sure you have moisture though. Seems like every ones in a hurry here in California, and yes some people hot rod (as much as you can an RX) in a Lexus. Ever read any of the posts about getting more power out of an RX? You don't need a COBRA to have brake fade however I can see that happining in a COBRA.
Sorry to get off topic luxury1.
