I've never met a police officer nuts enough to try and keep up at 170 honestly your biggest risk assuming you know how to pull off the highway and weave through traffic is messing up not the police. The slightest mistake at those speeds and you'll be dead half a second later. It doesn't matter if you're on 2 wheels or 4 you don't survive 170 mph accident on the highway. And the police follow at around 110-120 so they don't kill someone else on the highway.
