I really dont know why people are so afraid of making red sharp turns when you have a white K-turn.
I would not care if the Defender had at least one green bank, but having only straight ones and the fact that I hate being stressed for more than one turn, I'll avoid the situation as much as possible.
But the real reason of Adrenaline Rush is to be able to do a sharp turn 1 and then barrel roll with a Defender once per game. I think it's worth 1 point.
