Overheard conversation at a rest stop somewhere between Bakersfield and Vegas.

Woman: That must be hard to be a biker (motorcyclist).
Daughter: Why?
Woman: You're going 80 mph and you get all these bugs flying in your face.
Daughter: That's why they have helmets.
Woman: Plus it's kind of dangerous. They should invent a motorcycle with an extra set of wheels and an enclosure.
Daughter: I think that's called a car.
