In my opinion, it was Driver B's fault clearly. Driver A just fights for his position, but what driver B does is just not fair. First he just deliberately dives into the line of Driver A and gives him a not-so-slight nudge, and Driver A is lucky to catch the car. Then, Driver B tries to exploit the consequences of his nearly fatal move by driving a completely ridiculous line, causing him to crash into Driver A.
Driver B did not only violate the gentlemen-racing-rules (not giving room to someone after a closely avoided crash), but also did not use common sense: By thinking about it just for a split second, He should have known that, by driving over the grass, he will get carried out of this corner wiiide - there is no room to get carried out wide however, since Driver A is there.
