I agree with all. Having driven a big rig many years ago, for my dad's bakery, I can appreciate the work involved and how upset drivers can become with crazy 4-wheelers. On the other hand I've seen drivers of semis do some pretty crazy things too. More then once I've been driven off the road or into the median by a driver not paying attention or for some other reason. I agree with Trash that it wouldn't be a pretty site to collide with metal or a chunk of tire, while on a bike. Simple Solution: Give them respect, and a wide berth!
