I had the nerve to get it up to 40mph yesterday! I'm still getting used the handling of the 360, while it's a very nimble responsive car, it's soft suspension and rear engine give a "teetering" feeling going around corners, as though the car is tip-toeing over the road's surface.
And the brakes only seem to work sometimes in unison (usually it will pull slightly to one side, and the brake in the other opposing wheel will kick in after a short lag time) which seems to be a normal habbit of cars using such simple braking systems.
Still needs a muffler!
