Atlanta man shatters coast-to-coast 'Cannonball Run' speed record - CNN.com When they were moving, which, impressively, was all but 46 minutes of the trip, they were averaging around 100 mph. Their total average was 98 mph, and their top speed was 158 mph, according to an onboard tracking device I think this bullshit, unless there is some secret superhighway I do not know about. I travel from Texas to East Coast several times a year, it is impossible to not run into weather, traffic, accidents and other things that slow you down. I can barely average the speed limit. And not a single cop saw them cruise by at 100+? Or every one that did, did nothing. NFW. Sure, there are patches you can easily hit 158MPH, even 200+ but to average 100 MPH is almost mathematically and statistically impossible. I would love to see a GoPro video of the entire trip proving it.
