Are you suggesting mandatory training simulators for operating car navigation systems? Or are you insinuating that I'm somehow incompetent because I attempted to use a GPS in mid trip?
I'm saying, specifically, that it would be utterly terrifying if commercial airline pilots engaged in that kind of behavior: you took it personally for reasons only you could know.
You taking your eyes off the road to fiddle with a GPS could, at most, kill the handful of people around you. A pilot flying a 747 with his head up his ass could kill a shitload of people, and cause massive amounts of property damage, depending on where he crashes.
chill out on the internet insults.
You need to 'chill out' on the emotional responses. FYI, that wasn't an insult; if I wanted to be insulting, I would have substituted the word "guy" for something with a bit more punch, like maybe "narcissistic fuckhead."
They may be easy since they're semi-anonymous and it can be fun to pretend you're smarter than your target, but since you don't know your target, you run the risk of insulting someone much smarter than yourself and you could end up being the one looking foolish.
Kinda like when you make yourself look foolish by lashing out at a perceived insult, when the person you're lashing out at never actually said whatever it is you decided to be offended by, huh?
