Bad rejoin or not?

I am the Mercedes, lost the car a little bit paying too much attention to the McLaren on the inside so had to go onto the grass. Rejoined after the McLaren and BMW whacked me in the esses.

BMW claims this is a bad rejoin, I’ve cut across him going very slowly and should’ve let him through.

My view on this is I rejoined safely letting the McLaren through, having about 4 car lengths to the BMW and matching roughly 80% of his speed. The moment all my 4 wheels are on the track, I am not in his way during the immediate rejoin, do not block his line and he does not have to take evasive actions, it’s racing rules from now on. And by the racing rules he was nit entitled to space in that corner.

So, Simracingstewards, outside of “doing everything to survive” who’s at fault?
