WASHINGTON (AP) — In some ways, computers make ideal drivers: They don’t drink and then climb behind the wheel. They don’t do drugs, get distracted, fall asleep, run red lights or tailgate. And their reaction times are quicker.

They do such a good job, in fact, that a new study says self-driving cars and trucks hold the potential to transform driving by eliminating the majority of traffic deaths, significantly reducing congestion and providing tens of billions of dollars in economic benefits.
