Driverless cars hit a big bump, literally. We recently learned in the Huffington Post that Google's testing of their driverless car prototype hit a municipal bus in Northern CA earlier this month. And while no one was hurt, it does hurt the program. As to responsibility, Google claims some of it was their fault, but whose fault would it be if it were a serious or even fatal accident? For now, a human driver is definitely needed.
Still, car manufacturers should continue with cars with driverless support such as help with double parking, self-braking, and other safety measures. But a completely driverless car, without an attentive driver, will take many, many more years till fruition.
