We've seen no evidence that he has been threatened.
His biggest issue is likely that his job makes him reliant on being on social media, but now his name is leading to lots of videos of him intentionally knocking over a cyclist.
There have been aggressive and nasty posts in various places, here's one from the Ducati forum (and possibly from someone on here) that is over the top.
"I believe you have a family, right? How many kids do you have? What are their names? Well, I hope one of your children is subjected to the kind of behaviour displayed by yourself in the video. I want to see how you like it with the sidi on the other foot.
... <snipped> ...
But please do report how it feels to have someone close to you hit by a machine controlled by a know nothing bully, please, I really want to know."
If the Ducati guy can point to many similar personal attacks, and I'm sure there have been worse, it may give him the opportunity to persuade the authorities that
a) he is very sorry for what he did,
b) he has been forced to close down every social media account he has, including LinkedIn, thereby seriously undermining his ability to gain new work as a graphic web designer,
c) he may have lost current clients, blah, blah..
all of which shows he has been sufficiently punished for his actions.
I'd rather the vein-popping online attacks stopped so that he could be dealt with properly, hopefully resulting in a conviction and several points on his licence, if not a disqualification. That will send out a better message.
