I'll say this.... There are far more incidents related to other activities that happen far, far, far more often that street racing that are actually more dangerous. Texting and driving, too sleepy while driving, drinking and driving to just name a few. And those happen all the time.
Having said that I do agree to a certain extent with you. If there's a place where there is no one around, and there are people up ahead spotting for oncoming traffic, and the lanes are not on a residential part of a highway, no other roads intersecting with that road, and no way for any third person or party to get torn up... Then I say ok go for it. But let's be honest... That probably doesn't happen very often at all. And that is wrong and totally stupid.
I don't mind people driving 100 or more mph down the interstate either. If there's no one around at all then I really don't have a qualm with that. Far, far better no one else is hardly around versus having a decent number of other people around. Like on July 4th night this past year. I am headed east bound on interstate 64 and these two cats come rolling 100 mph. I am going 78-79. I get out of their way. Then two more world champions come up going 115 I'd bet. Going around the slow right turn near exit 220 and there's a vehicle in the right emergency lane. Blue lights come on. State police officer had to chase down one of the champions going 115. I laughed a lot at that. And I was not pleased with them champions either. Because there was a good bit of traffic out that night at 1 in the morning due to it being July 4th night into the 5th am. That was what was stupid to me. If those morons had been out there on say July 20th on a Thursday at 1 am with hardly anyone at all around... Still really dumb and stupid. No doubt. But at least there would have been far, far less other people on the road. Thus greatly limiting anyone else exposure to those Champions.
