I was thinking about the following...
The tracks we drive are rather old and presumably designed for the cars of the day. Thus our lower HP 911s do a great job. In fact, we hit the red line at certain points through some of the turns (by design?). I imagine these tracks to be wholly different (less exciting?) in a higher HP or newer with all the bells and whistles (wider wheels, bigger brakes, traction control, etc.)
Then I got to thinking about golf courses. Newer golf courses are designed to be longer because the technological advances in the equipment (if not the golfer) make the older courses too easy.
Since I guess there are far fewer tracks built than golf courses each year (decade

), how much do they factor in the cars that will drive on them when designing the track?
