Why post your personal experiences and thoughts when so many on this forum don't have the sense to accept those thoughts and just keep "arguing"!!! Just sayin!! So here is my "argument":
As to slowing to allow merging, it's not the vehicle on the hwy that has the burden of yielding, it's the "merger" in any state. So some think that a 54 ft long tow and trailer locked in the right lane with vehicles right behind and along side should "slow" when a "merger" comes jamming down the lane. Yes, you can and maybe is best to, move to the left lane, but when you have no way to do that, do you slam on your brakes to give the other idiot the right of way???? How many accidents on the freeway are caused by that? Used to have yield signs on the on ramps to remind the "merger" of his responsibilities. Guess the big city drivers don't need to follow the normal, safe practices. Always in a hurry!!!
