Your Worst Beat?

I was at a red light today in the left lane. I had about a quarter mile before I entered the freeway on my right. As I was about to switch lanes, a silver 350Z banged past me. I of course floored it and got behind him. The on ramp is nice, tight 270 degree beaut. Tight enough that above 35 mph your tires squeal. On the initial turn in, I gained a car length. Then, just past the apex, this hoon hung his rear out (causing me to hit the brakes), got pointed straight at the freeway and BLAMO! He was off. As you really can't break the WRX's grip on dry land, I was cooked. But that's not my worst beat. A few years ago I came upon a red light and an E46 M3 on Sunset Blvd. It was around midnight and I was stupid enough to rev my engine. I had him for maybe 12 feet. Then the shame showed up. You?
