How hard is polytrack when you're always accelerating?

Today I tried playing Polytrack, but I was always accelerating. I've done this before, but this is the start of a new series where I do it on every single map. I did maps 1, 2, and 3 this time, and I'm looking forward to the rest, but I'm also a bit scared that it's only going to get harder from here. If you had feedback, please comment it.
