I've seen more dangerous at 20mph...
I totally agree with Chris Collins. While he was going fast, he wasn't doing a ghost rider thing of weaving in and out between cars. He wasn't "forcing traffic out of the way". Yes traffic got out of the way, but I very much doubt that if they stayed in his lane that he would been able to do much about it. It's quite nice to see drivers that weren't hogging the outside lane for once.
