I can stay parked at a green light the entire cycle, and it still will be 100% the fault of the person who rear ends me.

As for what I'm doing, it's probably something like scrolling the map to see what road I'll be turning on in 5 minutes, so that I don't have to look at it (regardless of whether I'd be touching it) later. Or a dozen other similar things, none of which have anything to do with social media.

And I know you, as a reasonable adult on this forum, know this.
