Individuals are largely shielded from taking responsibility for the dangers and costs of car crashes in the USA by special exceptions and allowances. Companies and commercial renters are not so protected. That makes consumers drastically underestimate the real costs of their car use and RelayRides is going to face a hard task in keeping it covered up for their individual providers.

Both civil and criminal liability for killing and injuring others with a car non-commercially are incredibly cheap. The usual penalty for killing someone with a car is no penalty at all, even though over one hundred people a day die from driver negligence.

I agree. The solution is fewer restrictions on tort liability, not more. If people bore the costs of driving, they would drive less.
