To be clear, I've been watched NUMEROUS times by the County and TSP doing 50-55 and NEVER been pulled over. Darrly (who you meet in that video) will tell you the secret:

1) Don't tailgate
2) Don't pass
3) Don't act like a jerk in ANY way at all
AND
4) DO NOT cross or touch the yellow lines.

I was running with a few others back in 2011 or so, where we were following a van at 20-25mph, he was over the line all the damn time. The law went by us, turned around and came after us - and stopped the van.

Stay the hell away from the yellow.
