I used to object to the idea of driverless cars. Then, while driving around NYC, it occurred to me that driverless cars, however reckless, would be an improvement over the other cars on the road. In fact, not just in NYC, but wherever I've driven across the US driverless cars would be a step up.

The driverless cars being tested now drive more deliberately and consistently, if a bit slower. This means that accident rates should come down, and with them the collateral congestion that they cause, hence effectively increasing the average miles per hour of a commute.
