I'm not sure what you mean by that. Do you mean super un safe cross country races? Its called rallying.

Do you mean impractically long drag races where lol turns out I wasn't flooring it and now I'm really flooring it? That aspect of redline doesn't make any sense.

Or maybe just the competitors build their own cars and anything goes? I could get behind that. Racing seemed more pure back when it was dudes who built their own cars in their own garage.

Sorry for the confusion, I was referring to a movie https://en.wikipedia.org/wiki/Redline_(2009_film)

There's also a film by the same name about racing, so there might be some confusion https://en.wikipedia.org/wiki/Redline_(2009_film).

Well, it's still that. But now the dudes have a crapton of money.
