Let's say you find some crazy fast ballasts. The fastest I know of are around 6 seconds. At 60 mph, you're going 88 feet per second. Assuming the other driver has cat-like reflexes, they might take 2 seconds to notice the ignition and warm-up happening, and hit the brakes. That's 176 feet. You just got hit. Additionally, you just got cited with the accident.
If this were even remotely a good idea, you'd be reading about where I did it a year and a half ago.
