I found out you can pass two-lanes traffic with only one jump (for the finish) if you align more than half of your car outside the left road (at the right of the left road).
This might be a strategy for perfect time on it, but it took me 7.58 to pass it that way, since i couldn't do the alignment part quick.
I aldready implemented that and got it perfect so no optimization here i don't think sub 60 is anywhere near possible but it could be attempted by saving time on sharp edge and criss cross with perfect movement.
btw if no one find out yet you can double jump once midair because the jump refresh reset right before you hit the death barrier so lilypad for exemple is litteraly a straight line
