Well, the chance of that happening is obviously 1 in 1000000, but the chance of it actually happening when coming into your driveway is too slight to measure! :BLAA:
(remember, even though the odometer only goes to 999999, it starts at 0....)
Cool, I parked my car at 99999 not too long ago. Just got my bike in march and already have 3400.. I suppose the thrill will wear off eventually. Or won't it??
