You ain't very bright. I stated that they gave chase, not that you were running. I used 80 or 90 mph as an example, precisely because those speeds are only a little bit over the legal speed limits in many places. So, you meet a cop on the interstate, doing around 80 - in many places that is just ten mile over the speed limit. The cop drives across the median, does his U-turn, and gives chase. HE EXCEEDS 100 MPH, so he tells the judge that the "chase" exceeded 100 mph, in an effort to make the arrest sound much more serious than a similar arrest in a 35 mph zone.
As for "running away from the cops" - well, maybe I have done that. You don't do it in the family car though. And, "speeds over 100 mph" are meaningless terms on/in any vehicle capable of outrunning a police car. The term "speeds in excess of 175" might make sense then, except very, very, VERY few police cars are capable of that.
Youtube has a number of videos attributed to "Ghost Rider". You might find them interesting. Note that not all of those videos are of the "real" Ghost Rider, but some of the false attributions are as good as the real ones.
