i drive a car. that car might crash. the roof might cave in. the engine might end up in my lap. the side-guard door beams might meet in the middle of the car and crush me. i've decide to stop worrying too much about it. some cars are safer than others, yes, but i'm fine with my ignorant belief that my car won't let me down if it decides to do a cartwheel into the ditch. happy motoring!
