One of best things I've ever beaten

I really wanted to finish this one but when I saw the fourth lap I just surrendered. The first two laps were fun, but the third lap took me like 3 hours, particularly at the last section. When I finally got it I was so happy because I thought I'd reached the end. The change of music was quite fitting for that moment! Well I suppose I could try this again some day and probably catch back up to lap 4 more quickly, but for now I've endured enough pain.

Found a problem with this level: sometimes my car explodes when I land on some of the bigger platforms. I guess there's a laser grid inside them just a little bit too close, and when the car lands at a certain angle it touches that laser grid.
