Looks like somebody never learned to respect his elders.
Yes, we do tend to always favor the operator of the motorcycle in situations like these, but when you chase down an elderly woman and chastise her for essentially being a challenged elderly driver, and there was clearly no malice on her part, you look like a raging dick 10 out of 10 times.
One thing’s for certain, though, this dude’s lucky that wasn’t my grandmom behind the wheel. She would have jumped out of the car and knocked his helmet clean off with her cane. Cataracts, bad hips and all.
