I came across that video a few months ago too, and thought the same thing about the flip-flops and shorts. I may take the rare jaunt with just my t-shirt when its real hot, but I'm always wearing jeans at the very least, and steel toed boots of some flavor ('cause work pays for 'em!
).
And is it just me, or does his idle sound a shade low?
Lacking a tach, I may have set mine a little high, to avoid the risk of low oil pressure, especially when stuck in traffic in the summer.
