i didn't watch the video, but it sounds like they just drive the speed limit and block all lanes across. which is stupid. it proves nothing.

everyone driving the speed limit DOES NOT EQUAL four idiots blocking all lanes at the speed limit, while everyone else tries to speed.

the truth is, although the limit could be higher, if everyone followed it, there would be less traffic, less accidents, less gas wasted, etc. that's the point.

and besides, i speed to work doing 85, vs. cruising at 65, and it makes no real difference in how fast i get there. however, if i get into an accident, i'm going to cause a huge backup, which i'm more likely to do at 85.
