cool things (auto)

How the thing works: Look to the right. the first one shows you how to keep something that swings back and forth flat. However, the two swinging arms cross over each other, so we add a third one (look to the right) to keep that from happening. Look further right. We can use hydralics to pull it up while keeping the thing the car goes on flat. Furthur right, you can see that I use gravity to pull it up, using a weight instead of a hydralic. This is basically what I did, just that I did it with one things car holder connected to the second one's swinging arm's start point, as you can see to the right. This is basically how the whole thing works. By the way, the car below is meant to be a timer so you can see everything.
