Thanks for the information guys, I just had a look through the thread on the PCars forum ....
From a quick look (cos it gets off topic fast in that place) they have AI controlled pits so people can't run over unanimated pit crew members.... what the hell ? is that seriously an answer ? I've noticed Ian Bell is a bit of a twat at times towards his paying customers, but seriously, that's seems like a piss poor excuse to blame it on licensing. It's not like the game is simulating vehicular manslaughter, AI aren't getting hooked up in the wheel arch and dragged down the back straight with blood spraying everywhere, although Carmageddon is pretty cool.
What about the fact I can simulate driving my car in to a wall at top speed and committing suicide, even though the animations aren't there, shouldn't that ability be removed also ? Maybe this game should just be on auto-pilot and we can watch how racing sims should be done.
edit: After reading further, it seems like they will be adding animated pit crews in a later build. Which would lean towards, It's too hard to animate crew and allow you to drive the car in pits at the same time, which makes more sense than a licensing issue. Still, drivable pits>animate pit crew.
