No friction on the start of the ramp in Big Air
I'm not sure if this is intentional or not, but to me, it absolutely looks like a bug. It makes no sense why that part shouldn't grip at all. It also makes that every single attempt, you jump over that, to try to not hit it.
It's quite easy to see where it is, when there's brown smoke coming, there's no friction, and when only the exhaust is visible, it's grippy again. Also, the little bump that's the 'transition' between the starting flat and the hill is grippy too. Seems EXTREMELY odd that one single part shouldn't grip, when everything else does.
