Pulled out onto my road and was doing 35 in a 30 just to avoid a speeding ticked. Some black SUV with 172 as first numbers of his plate sped up and got on my tail. He then passed me close forcing me onto the shoulder. I gave him the clear middle finger and he pulled over. So I pulled over the side of him and parked the scooter. I put my face to his window and yelled at him I was doing 35 in a 30. He yelled at me for driving an unregistered vehicle (justifying possible vehicular manslaughter).
I yelled 3 times back that I didn't have to be registered; and after the third time telling the idiot, he took off real fast.
He purposely ran me off the road thinking he was in the right because my scooter wasn't tagged.
An easy way to get the upper hand is say "I got it all on video. Let's call a cop over and see what he thinks", while you pull out your phone.
Yelling with motorists has escalated into violence before, and adjusting side mirrors just makes them hate all motorbikers, so it's best to avoid emotional behavior. Definitely speak up to them though. I've gotten apologies before.
Which dash cam did you get? I'm looking for an inexpensive, low maintenance one that's easy to plug in & remove (People 250).
