1. 35pds. vs. 35pds.-25T(bike to 18-wheeler). Other than another cyclist, a close pass by a motorized vehicle is definitely dangerous.
2. Yesterday I was on a 30mph two-lane blacktop during PM-Rush. There was a truck behind me carrying one car, and towing a second car. He honked, then passed me. Just to make a quick left turn into a local used car lot.
I immediately followed him and told him. Not only about my legal right to 'take the lane'. But also about the fact that that there is a blind curve soon after the lot, and that he did not signal his turn.
I could have been 'collateral damage' because of his needless rush.
