Concrete buckling

Anyone see the clip on the weather channel with the S"UV fling through the air in Wi. ? I believe road concrete must be about 8'' think and the road ended up being tent shape with the bottom of the road above where the surface would be. That SUV must of went 5' high at about 65+ mph through there. I went through there 4 hrs. before that an it ws cool enough yet were the road was good. Also over the overhead about a 1/2hr. before that happened. With the temps around here not the hottest but 92-97 I wonder why I dont see many bikers out. Think maybe they are learnin that when its that hot you cant even stay cool on a bike.
