Looks legit to me. Google suggests that's the correct office for the CTO.
Can't explain why it came to you though, is the car definitely in your parent's name?
Yeah, seems legit based on the details its just confusing, the car is definitely registered in my dads name, I checked the V5.
Generally just annoyed with myself as I've never had any points or had any trouble before. There's an FAQ type sheet with it giving the speed ranges and requirements to qualify for a Speed Awareness Course, which I qualify for, so hopefully I'm offered that.
Is it worth requesting the photo/video evidence or should I just get on with it?
