It's possible that the Focus driver thought Squirrel anf the Skoda were racing, and panic set in.
They might even have thought that braking as soon as they saw the exit from the bend was the best way to get both following drivers past ASAP

If Squirrell was looking to pass and the one in front was in a low gear it is likely that the engine braking kicked in for a short time before the brakes were applied, all of which could give a
perception of harsh braking that was in fact just a practical (but misguided) indication of being prepared to be overtaken and facilitating same.
I can remember in the earlier days of my courtship with June. If ever we went anywhere in convoy for whatever reason, she was in front if she knew the way (as I was a better catcher-upper), but I led if she was unsure of directions. She used to hang back for all the right reasons and I used to make every available opportunity for any leap froggers to get past me too. If I felt that, for whatever reason, any leapfrogger had wronged her (I did once or twice), I was sufficiently red misted to teach them a lesson - which could well have included me boxing them in behind me by braking when I thought they were close enough that they'd be unsighted from oncoming traffic. I;ve grown up since then I hasten to add, but it could easily have been a young courting couple in convoy that Squirrel temporarily split up.
