See because when motorcyclists say “share the road” what they really mean is, “go fuck yourself. We have an expectation of doing our own rules, while you have to Maintain your rules and our rules, and if YOU fuck up either our rules or your rules, we’ll sue you because even though you looked twice and our loud pipes saves lives, you still weren’t expecting a vehicles driving down the painted line that you as a automobile driver have been taught since day one, shouldn’t be driving down.”
I think that’s what that bromide means.
Using motorcycle logic, I can drive My dope-ass Kia Forte anywhere that it can fit as long it’s an expression of convenience for myself.
