double yellow or not, you pass when it's clear, not when you feel like it. A dotted line is not a free ticket to pass, you still need to assure you are clear to pass... I'm not a "father knows best" but the dotted/double lines are there for a reason... Right we have better acceleration and more agility than a car, but still, if you see a double yellow it's just more reason to MAKE 100% SURE you're clear to pass.
