No more door slam

Last time I had a passenger at the track with me I realized they have to slam the door to get it to shut. I spent a lot of time thinking about the best way to address this problem. Checkout this guide about it: https://github.com/amarjandu/s30/tree/master/door.

ps. I'm in progress to move my how to information here, to make sure it says up even if this website goes down.
