Then it would be like watching the NHRA.
Grudge/Street racing is just as much about the trash talk, as it is the actual racing. It's all to get into the other guys head, and make him do what you want.
Around here, it's not so much about having the faster car, it's about winning that $$$. A big part of that is the psych out game. Get the other guy to give you the race you want. Back tire stage, car lengths, the break, the clear, etc.
It's also why most grudge/street race have stipulations.
" a chase is a race" is a good example. if we are leaving off an arm drop, and i leave before he drops his arms, and you STAY there, i jumped.
However, if i leave before he drops his arms, and you FOLLOW me, then the race is ON, i didn't jump, because you chased me. That's done so one guy can try and leave early, and hope the other guys follows.

I've seen many races where the slower cars wins, all because of the spot/stipulations. I've also been paid well for it too. :-)
