I may be wrong, and i'm still working this out as i type, but that was a 60 limit road, so lets assume the car that the biker overtakes (at 1 second in) is doing the limit (likely). The bike is travelling 40 mph faster than the car and reaches the junction 4 seconds later to meet the car, that mean that the car will have been about 7 or 8 seconds from the junction (200-300m?) when the clio started to manoevre, 7-8 seconds is plenty of time to execute the manouvre and she would have done so if we remove the bike from the scenario.
To be fair, i wouldn't imagine the car being on her mind at any point after she had hit the motorcyclist (or he hit her). I'd imagine she'd have plenty of fear / hurt etc going through her mind to think about whether she had seen the car, let alone the bike.
I am not saying she's totally guilt free, but that biker certainly contributed mostly to his demise, and the girl has to live with those consequences for the rest of her life, even though she is not totally at fault.
I've covered this;
100m takes 2.3 seconds to cover at 97mph, 3.8 seconds at 60mph
The car cuts across the give way line less than 2.5 seconds before impact (so bike would be approx 100m away), and would have taken more than 1.5 seconds further to clear the carriageway.
Therefore, even at 60mph for the bike, the car would still be in the carriageway. Bike would have been able to avoid the tail of the car, but the car should never have started the manoeuvre - it was simply dangerous
Clio driver was male, btw
