This may not apply here but this issue came up many times when I lived in the UK. Some dudes may have been seen by a cop in one stretch of road and radioed it ahead to others, or bikers stunting were caught on camera from the front, or they had their plates covered, and it is always near impossible to nail a biker based on face recognition as you can fall back on with a car driver. So they used "distinctive gear and markings" as equal to face or license plate. Since this dude is up on the net doing something illegal and if a cop downloaded the pic, all they have to do is match him up if they see him on the road. He (the biker)will have to prove that wasn't him on the bike, because his bike is ultimately his responsibility, so they will persist in demanding he provide evidence of who was on the bike. If he doesn't that can be another charge of obstruction, and you see where it can go from there.
i.e. if it was stolen he would have had to file a report, if he lent it to someone he would have to provide information in an ongoing investigation, or face the charge himself because they may have enough to convict him on it.
If a buddy of mine borrowed my ride, and now I'm the one facing impounding, loss of license and thousands of dollars of fines, hiked insurance, etc, how silent do you think I would be? So playing dumb with a cop when he catches you with evidence might not drop the scent off you!
I have been mugged before and given a description of the mugger's clothes and they were picked up on that alone over a week later! So I know cops can nab you (in Toronto at least) based on description of clothing alone several days after the incident.
What makes this easier for cops is how distinctive this guy is...and that bikers often wear the same gear day in day out and cover the same routes of travel.
With the new anti-stunting laws you really don't think a cop might set an example or least try to set a precedent?
