It is conceivable that renting your car to a complete stranger, who might be a reckless driver, could result in serious harm to others. Even worse, in this case, RelayRides makes you partly responsible because you are allowed to interview the renter before agreeing to hand over the keys.

There's an adverse selection problem with RelayRides: terrible drivers who cannot afford or obtain auto insurance will be over-represented among their customers.
