Don't generalise a very large group of workers. I know the type of person you are describing and it's likely they are just a prick and there are lots of them in all kinds of cars. All I saw from that video was a bloke having a dig at cyclists, he did deliver the message in a manner with no class and I suspect he has none in any social situation, definitely a missed opportunity to have a very clever dig at the cyclists.
I'd have yelled out, "hey fellas, the bike track is smoother than the road, you should try it out!"
Let the better jokes he could have used roll....
