I don't like passing big trucks at all
Same here. If I pass one, I do it right smartly, get around him without delay. I will not run alongside one for any reason, if I have to slow down to avoid it , that's what I'll do.
I don't even like driving beside other cars on the interstate, let alone trucks. Even if the driver is competent, there's less room to maneuver. An animal running across the road, a thrown tire tread, and and it's much harder to avoid the accident, if someone is right next to you. I do not get these clowns who think they should creeepppp past a truck taking two miles to pass him.
The great majority of truckers are professional and safe. The ones that aren't stand out like a sore thumb.
