I have a lot of sympathy for the car driver.
The guy in the video had just finished a track day, took that speed on to the road and was riding pretty irresponsibly from start to "finish".
He is also a text book motorcycle accident:
Excessive speed for the conditions (in this case approaching a junction)
Right of way violation.
He wasn't particularly visible ie- grey motor bike, grey day, no high visibility clothing on a grey road.
Lack of anticipation by the rider.
55% of all motorcycle accidents happen at junctions and it's not just a case of drivers failing to look but rather failing to see the motorcyclist as in this case.
Grey bike, grey day, grey road, approaching at excessive speed from behind a grey car.
It's 6 seconds between over taking the corsa and hitting the car at the junction.
That's not a lot of time for the driver to see him, from coming behind the car, the driver probably clocked the corsa, (didn't see the bike as he was currently behind the corsa at a distance away) started to move off at a reasonable speed, was looking into the junction as he was driving into it and bang, some idiot on a bike tools into the front of him.
