170+ may be elite but 150 is not. There are too many fast bikes and too many dumbass bulletproof kids. As far as the land speed records I have to do more research on those. I don't know what all the acronyms mean. I do know that the interstate loop around this city sees people going 140+ on a weekly basis. My officer friends don't even chase them
Well one thing I point out to my kids is that there are lots of new "Crotch Rockets" and lots of old Mack Trucks.
