I’m also a motorcyclist (but hold the motor) and my experience is very similar to yours.

I almost got hit a few weeks back by a car driver trying to turn right on red whilst on a fucking Facetime call, with the phone held up right in front of their face. If I hadn’t been in a rush I would have let them have an earful.

Like, please don’t ever use your phone while driving, but if you absolutely have to be a despicable human being, can you at least look away from the screen when navigating through intersections??
