I currently have the #2 time on Zephyr Ridge on Toxic, less than a second off the top spot. The last corner is AFAIK impossible to get through without hitting a wall if you keep holding the accelerator when using the Barracuda.

My complaint isn't that the steering feels sensitive, but in fact the opposite - it takes too long for your craft to shift its weight or however, not sure how to put it.

The airbrakes seem like they give you sideways momentum in the opposite direction of the side you're braking on in addition to slowing you down generally, which seems the opposite of intuition. Have a go of lining yourself up on Ishtar's jump, go straight, hold the right airbrake and you will end up left of the landing, falling off the track. Oh and yeah, that corner leading up to that jump is another of those impossible ones.
