Of course you can! I said Pure, not Fusion

Fusion's AP actually is the worst thing you can do in a race, it flies you straight into walls and all that stuff. One time I activated it on the start grid (after passing by the entrance of the pit) and it turned around trying to fly back into the pit - it just crashed into the walls, though.
And above all it also slows you down.
It's a totally useless weapon on Fusion.
