-An ability to drop a barrel behind you. As in, while you're driving you press a certain button, and a barrel will appear right behind you on that spot, until someone runs into it. -An ability to give yourself a Nitro (just the same effect as picking up a nitro pick-up normally, and you can only use it once (unless you pay for a new one)) (I don't know if this one exists already - if so, forget it) -An ability to make your car invincible for X seconds (for example 30 seconds, but it should NOT be cheap). Yes, I've played too much Mario Kart. Also, I thought of this before the GC Shop even existed but Sprays (Like in Steam games). You press a certain button and a pre-picked image will appear below you on the ground. OR custom image on your own cars (should be hella expensive). Only if possible of course.
