No she didn't have time, even if he was doing the correct speed, she didn't have time so that's rubbish. You are massively overestimating it. It wasn't close to 4 seconds different. It's roughly 1.3 seconds, which as I said would move the Clio roughly 2meters forward. It's 3.7m long car, so still not even close to making the turn safely.
Where do you get this 1.3 seconds from? If the bike was doing the speed limit, he would still have been behind the car he overtook at 1s into the video. Which we shall assume was also doing the speed limit. The Clio executed the manoevre at least 7 seconds before the car that the biker overtook would have reached the point of contact. This is confirmed by the fact the car that the biker overtook was not involved in the incident at all.
