Some years ago, was talking with a LEO in one of the small burbs on Galveston Bay, off of highway 45, and he told me the same thing. He said they had a repeat offender on a crotch rocket, that would often run up and down 45, through their jurisdiction at 140+. They were advised not to chase bikes, as, while there is a danger to others, they are mostly just a danger to themselves, and a chase with police, in cars, was deemed too high a risk.
He also called those type of bikers, future organ donors, and said he had seen enough examples of those types of wrecks, to know how it ends.
