I feel for this poor bugger as I really feel helpless with some of these clowns on the road and I really have to work hard to control myself in these situations, however, I guess its still a good reminder to politely smile and let them be on their crazy way!
I find it very hard to adopt this philosophical attitude when 'they' are endangering me and other road users. I don't mind being overtaken, and I don't mind them writing themselves off, but when their action places me in danger, or others for that matter, it's a different story.
