it's not the oncoming drivers so much (after all, I'm on the opposite side of the road) as the drivers who are going to cross my path (most likely waiting to make a left turn from the opposing lane, or a left or right of of an oncoming side street).

If a light blinds or dazzles a driver before a turn, hopefully the driver has the good sense to make the choice not to drive when they lose sight.

I'm only going to be a second or two and then I'll be gone. Having that small bit of time of hesitation from drivers would be a good thing, no?
