Hello, I just finished a cool code snippet that's easy to implement (1 script). It lets you get in and out of vehicles by just pushing SHIFT-W-E and whatever is in front of you.. you instantly jump into.
It would be great if you could try it out & give me feedback as to how the timing is...distance you have to be from a vehicle, if you prefer just a get in/get out action, or if you want to move positions inside the vehicle (like a tank) as well.

P.S.This is great for fast competition games.
