 Yeah, which means I should have saved it.  Will comment later, maybe, 
 but I have stayed out since the other answers are pretty good.  Basically, 
 the friction constant isn't.  Take a look at 
 for the Physics of Racing documents or do your own experiments.  The 
 coefficient is not even the same front-to-back as sideways because 
 of the role of tire dynamics in 'traction'. 
 By the way, the best top fuel E/T was 4.665 (308.74 mph through 
 the timing trap) for the quarter mile (134.11 m) at Memphis. 
 Those performances continue to define just what a tire can do.

 Nah, that's where they go when they discover the concept of passing.  ;-) 
 After they get that down, they might move up to NASCAR.  =8-0

 I love F1, but I prefer to watch the time trials rather than the "race", 
 particularly since most of the feeds we see use only short clips of the 
 in-car camera during the race.  For real racing, you poor euro folks 
 ought to watch ESPN for a NASCAR race on a road course, since you can 
 do a lot more in closed wheel cars (like WSC) and the rules are designed 
 to have lots of close running (unlike WSC).  But the real thing is sprint 
 cars on a dirt track, or figure 8 racing.  The latter is almost as cool 
 as unlimited chain saw competition or street luge.
