I'm not arachnophobic. I generally leave most spiders alone, outside of Black Widows, Brown Recluses and Wolf Spiders. I don't really have an issue with tarantulas--in fact, I kind of like the creepy little hairballs.
However, when one crawls up out of the defroster and starts running around on my dashboard at 70mph, I don't like 'em that much. Yes, a bit of a freakout occurred, I pulled over and commenced swatting at him, and he lost a leg before disappearing down the vents again. Hopefully he left the premises, or at least died quickly. It was only an adolescent, and I kind of feel bad, but you scare the humans at your own peril, dude.
Funny how this has never happened to me before, and now, right around Halloween? Try and tell me I didn't just get punked by God. :)
