I too let it wash over me and I never get annoyed whatever is chucked at me it just ain’t worth the stress, I basically plod along religiously sticking to all speed limits and no more than 50 on a motorway and enjoy my day more. I find it really amusing watching people desperately trying to carve one another up just to get somewhere a minute or two earlier.
I watched with bemusement as a Halfords decker overtook me on a bend as I was going 49 in a 50 on a s/c and almost having a head on with a van, there was a d/c 2 minutes away ffs, the stress he must be under to have the need to drive like that !!
