1. Just because you have your blinker on doesn't mean I'm obligated to let you over. Especially if I have been waiting on traffic.
2. When you pull out in front of someone, it is your duty to accelerate rapidly enough so they don't have to let off the gas or apply their brakes.
3. No one should ever be allowed to pull an oversized load thru a metropolitan area between the times of 6:30 yo 8:30 am or from 4-6:30 pm. And your little flashing amber lights on your escort vehicle do not give you traffic blocking authority.
