In similar situations we have had people wave us on and we go ahead. They know why they aren’t ready to procede, I don’t. No point in backing up traffic. I have also waved others on when I was quite ready to procede. My husband does this frequently because he hates being tailgated and he really hates headlights in the rearview mirror.
Pretty much the only way I would go would be if he was in some kind of big-rig that needed alot of room to make the turn.
And frankly, I understand that people behind me might get a little ticked if they don’t get to their kids soccer game on time or whatever.... my opinion on that? Eff em. I’m not gonna risk my life, or others, because somebody’s in a hurry.
Realize I’m not the one that made this into an uncertain situation.
