Very nice, lots of potential.
- Holding right-mouse to aim the whole time seems like it might need some thought since I'd say you spend more time wanting to look around and aiming than you would wanting a forward-locked camera.
- Probably a good idea to consider controller support if it doesn't already have it because this could be good on console, might be hard to get right with the manual aiming though.
- Aerial controls would be nice since there are ramps, it'd be nice to be able to magically tilt your car so you land on your wheels.
- I have no idea what the pickups were doing
