As a fellow biker, there's no doubt the guy was travelling far too fast for the road conditions. No doubt whatsoever. But for those that think it was his speed that caused the accident, the points made below provide sobering reading
Apologies for the cut and paste but it makes the point very well
From the video the car starts to move when the bike is about 5 hazard lines away. Each hazard line and space is 9 m. So the bike was 45m away when the car pulled out.
45 m at 97 mph takes 1.04 seconds. www.wolframalpha.com/input/?i=45+m+at+97mph
45 m at 60 mph (the speed limit on a single carriageway) takes 1.68 seconds. www.wolframalpha.com/input/?i=45+m+at+60mph
45 m at 50 mph (about half the speed he was doing) takes 2.01 seconds. www.wolframalpha.com/input/?i=45+m+at+50mph
So the bike's excessive speed means he arrived 0.64 seconds sooner than he otherwise would if he'd been doing the speed limit, or 0.97 seconds sooner than if he'd been going at around half the speed. Look at how far across the junction the car was when the bike hit it. Would it have completely cleared the lane with a safe gap less than a second later? I don't think so.
So the car couldn't have to got out of the way in time. Could the bike have stopped in time?
The braking distance at 60 mph is 73 m. www.gov.uk/government/uploads/system/uploa...
The bike was closer than this when the car started to pull out.
The stopping distance at 50 mph is 53 m. www.gov.uk/government/uploads/system/uploa...
The bike was closer than this when the car started to pull out.
So even at half the speed the bike would likely still have hit the car. And he would still most probably have died or been crippled.
Hence, IMO, the car driver was largely to blame, as their actions would still have caused death or serious injury even had the motorcycle been travelling at less than the legal speed limit.
