For the ones you need a certain boost multiplier or airtime, you can do flips in place with Sir Colin at the starting line and catch up with the boost you get.
The upside down is weird, but this is just as fun as the original (which is a good thing :D)
...Incidentally, he goes forever if you get him high enough and just move to one side as fast as you can. Maybe not forever, but it increases your chances of hitting stuff. Haven't touched the controls in 7 minutes.
