Size definitely counted for more than speed
I don't disagree. I was just being a PITA (note my little "things are different in Mass" inertia joke!). I'm just being penzantic...or crafting a euthanism. None of my rotary/roundabout formulae are destined, alas, to make it into a college physics textbook.
I *do* hold my general generalities to be true....In Mass, the vehicle *in* the rotary only has right of way to the extent that the driver avoids eye contact and behaves fearlessly....in Germany the clapped-out VW Polo has supreme right of way over the shiney new Mercedes!
