Are you sure it was dangerous and not careless? I know someone who went through this recently, she was sentenced in May and got double the community service and more than double the driving ban for death by careless driving. Dangerous driving would have been a custodial sentence in her case but the reduced careless charge was accepted.
Anyway, my view for what it's worth. I originally thought this was the car driver's fault, until I found out the biker was going 97mph. Originally when I saw it I didn't even consider he was going that fast as I thought the video was to do with drivers being more considerate to bikers (which I'm for) but 97mph is just ridiculous and puts, not just yourself at risk but others as well. Bikes aren't always easy to see and it might be easy to make a misjudgement when you're not aware someone is going almost 100mph towards you. I'm all for drivers being more considerate for bikers as they are far more vulnerable to getting hurt, even at much slower speeds but this isn't what I took from the video. Slow down. It didn't have to be a bike in this clip, it could easily have been a car and the damage to passengers could have been the same, or worse (both parties could have been killed). If you speed like that then you make yourself more vulnerable to other people's mistakes. Slowing down doesn't get rid of the amount of idiots on the road but at least it gives you a better chance of surviving if it does happen.
The whole video freaked me out a little. Watching him just driving and overtaking, and probably loving every minute of it, and then all of a sudden that second when the car pulled out on him and you heard his yelp just freaked me out. You could be gone so quickly. Scary stuff.
