I've ridden with you, you have reflective strips and light and are otherwise brightly lit, or, at least more than me.

I hypothesize that the woman probably wanted to "beat you" to the driveway, totally misjudged how fast you were going and how much she has to slow down to make the turn. Sure, car drivers can accelerate to get past you but then then have to slow waaay down to turn. It happens all.the.time to me.
