I'm "that guy" and at 41 years of age offer no apologies. Whether I'm hauling a trailer, or just commuting, I obey the laws as best I can. Semi trucks aren't allowed in the left lane of 3+ lane Michigan highways. They tailgate and engine brake behind me to intimidate me to move from the center to the right lane so that they can break the law by speeding, hopefully unnoticed in the center lane. Sorry, but if they really want to break the speeding laws that bad, they can try their luck passing on the right, or take their chances passing on the left. Sharing the road means doing so within the law. BTW: I've seen 2 commercial drivers pulled over after passing me on the left. Thanks to them for helping my state pay its bills.
