Lock yourself up in a room with hundreds of harmless spiders until you're not afraid anymore. OR look for home remedies. I've heard spiders hate mint and lemon grass oil so maybe there's an aroma or something you can put in your car to get rid of those little buggers. Check Wal-mart or something... I'm sure someone somewhere has the latest "spider-be-gone" or something along those lines.

And you've gotta wonder if freaking out because a spider touches you is worth crashing into a bus full of orphans... j/k
