I like the interpretation given that the song is like 502, and it's probably right.
I like seeing other meanings in Megadeth songs too and think the song could be about pushing limits in general. The phrase "fast lane" also refers to a fast, hectic, or break-neck pace or style of living life. I hate to fall back on Megadeth song meaning tropes, but I could also see this relating to substance and drug abuse, not that every instance of "white line" has to be a cocaine reference but the thought crossed my mind.
I could see it relating to the lifestyle of a touring musician. I could also see it referring to other risky or dangerous behaviors than just outrunning the police. It could be attempting to beat a land speed record or flying a jet. Supersonic speed is probably metaphorical. Supersonic speed is usually associated with aircraft or ballistics, but supersonic speeds have been achieved on land as well.
