The real answer is, it depends. I don't really advocate stoplight racing because in most cases someone is going to get hurt. That said, its still way to subjective. Was the other driver really trying? Mostly you don't know. If so how far did you go 1/8, 1/4 a mile, it matters, because at some point someones common sense, or fear of arrest, or accident will allow the less sensible (I'll admit to being on both sides at different times in my life) to "WIN". Our cars were not built to be "RACE CARS". If you ask DC it was designed as a two seat touring car. Much like the TC or Reatta. The car is fast under certain conditions. For the money its hard to find one that does everything (accelerate, handle, brake, gas milage, while looking this good) as well. There are lots of cars that are faster in a straight line, will pull more g's on the skidpad, etc. The bottom line is think about why you bought the car. Whatever tipped the scales for you that is what you should dwell on. Otherwise you're going to wind up not liking your choice for what is probably someone else's reason. Drive your car and enjoy it and don't dwell on what it won't do, be happy with what it does well.
