In short, yes; it is absolutely worth it!

A perfect example happened today at lunch. I'm sitting at a stoplight where there are 2 lanes, I'm in the left. The right lane ends about 1/4 mile up the road. A couple cars come up behind me and wisely stay behind me in the left lane. That is, until an orange Mustang GT (not sure what year, but current body style) jumps into the right lane and times the light to get a bit of a rolling start. I mashed it and took him by a very easy margin. When I jumped in the left lane up ahead to make a left turn, he passes by me with his thumb up out the window.

Immature? You bet! Will I be grinning like an idiot the rest of the day because of that? Absolutely!
