Dumbassery checklist:
1/ Riding on shoulder because impatient. In a construction zone nonetheless.
2/ First rider can't handle some bumps in the road without just effectively falling off the bike before the bike was even really out of control
3/ Rider behind way too close for road conditions at hand.
4/ Rider behind makes basically no effort to even slow down or swerve, piles into the downed rider and crashes themselves.
5/ Both almost end up squished under an 18 wheeler.
Some people, I tell ya.....
