"Hate crime" involves presuming to screen the thoughts, and is always ideological rubbish. "Crime" rightly understood involves witnessed (seen or heard) or provable actions only.
As for "was he driving too fast?" You just pulled that out of the hat. If he had been, you may be sure it would have been part of the story.
According to this account (which is all we know), he didn't speed up. He pulled over and called 9-1-1. That would involve slowing down to a atop, I would think.
It’s the hate crime that’s the crux of the story. I don’t believe at all we are getting the whole story. Anyone could go on and on about the vagaries; was she poking or tapping him on shoulder? etc. We probably agree on hate crime, but equating poking with battery is one step closer to getting this woman convicted of a hate crime, which would be a real crime in my mind. But just my opinion.
