I don't suggest you be an ass and flash everyone on the road but I don't think you will see a noticeable loss of lifespan from the bulbs from normal use.

edit: I've never tried holding the stalk back when the headlights are off so I will check that out tonight.
Yeah I don't do it often, but I feel like every time I do it, I'm giving the bulbs the paddles are something. Massvie paranoia.

Yeah check it out, all 2010+ HIDs do it I think. I think it's stupid.

Umm.. I suppose? Unlikely though, it's usually an aftermarket job that does that.

They take .01 seconds to bright up.

@412 Horses. Ford even calls it "flash-to-pass" in the manual. My condolences for the idiot drivers in your area, but they are there for a reason, like letting someone in or, well, flashing to pass..
