Having watched those angles again, I think the following;
Turn 1, LH fault, went in way to hard and late, and his actions caused the contact between KR and HK. It wasn't the same as a normal turn one, much to banzai and risky, as evidenced by how far he went off track. (he might have even been done for a dangerous re entry on to the track, as you can see that RK had to take avoiding action)
Turn 11, I reckon that FM was put off by JT going into the corner, and was aiming to pass JT, when LH went down the inside of him. It also looks like LH tried to tighten the line on exit in an attempt to close the door on FM.
Turn 1, Racing incident, I can understand how both driver could think that they where in the right on it, but I would like to have seen the on board from SB's car.
MW Vs. FM I think that MW has tried to defend, as is allowed, moved across to block an inside run, he's then lost sight of FM in the mirrors and has moved over to the right a bit further (assuming that FM has gone down the LHS of him) to try and find him in the mirrors and not realised that FM was on the inside of him.
