The draft in this game is unfortunately not accurate. The idea that you get in the draft and get basically a shot of nitrous and speed past the car in front of you is completely inaccurate. The game does not pick up the effect of side draft, or the fact that two cars LOCKED together, become one single entity in the air. Sure, the game recognizes bumpdrafting, but not like it should. Aerodaynamics are also not 100% accurate. If that were the case, I should've been lifting off the ground in the vette at La Sarthe. Since curves like that increase lift, not downforce. Another thing, is that they don't represent bumpdrafting 100%. If I bumpdraft a car in a straight line, I HAVE to hit it dead square in the back, or else the bumpers wouldn't lock and would send it flying. Or even at Daytona, I should hit the car, in the right side of the bumper, which will push the car in front around the corner, not straight, meaning less turning on his part, and more countersteering, then turning left. The game does not recognize this, and will simply push the car in a straight line no matter what. It's unfortunate, but we do the best we can, with what we have.
