Looking back at the article, it does say the woman has serious injuries.
I don’t know about the laws in Colorado, but in Ga you can’t get the criminal conviction into evidence unless it’s a guilty plea. However, if he’s driving recklessly (70 in a 30 mph), he can be subject to punitive damages.
If he was drunk or high, then he may have an argument she accepted the risk. He may also have a defense that another rider was acting in a way that caused the need to speed.
But, yeah, generally, you are correct. There’s just no such thing as a slam dunk case for plaintiffs getting loads of money in my opinion.
