The game is supposed to simulate reality in a way which the
average gamer can handle (if realism is desired, as in many 
historical or present-day games).

So it is a bad idea to use an aerodynamics textbook as game
rule, but it should be used by those who write the rules to
get the rules right. And we're talking about changes to 
Vehicles, i.e. rule writing.
