I always get nervous driving up on ramps out of fear I'll drive off the ends. I had a pair of ramps with very deep intents at the top so the car would slow down on it own. That helped a lot. I have one suggestion for you ramps. Route the edges of the first 3 steps to make it easier to drive up and put a small thin block on the edge of the last step to keep the car from rolling back.A really simple project, and still, the video manages to add value with the idea about putting the handle at the center of gravity. Nice!
