I'm starting to hate the last couple levels ( Example level 17). On level 17, there are lots of ridges and gaps, which, no matter what vehicle you choose, succumbs to it and slows down the whole vehicle. It's a problem for me, and probably many others. I'm not saying it's impossible, but it's darn difficult.
