Setting the course for driverless cars

President Obama doubled downon driverless cars this week, declaring that the federal government, not the states, should oversee the development of self-driving cars, trucks and buses. The president and Transportation Secretary Anthony Foxx said that autonomous vehicles are too valuable for public safely and technological innovation to slow down with state-by-state regulations, or lengthy rule-making processes. And besides, self-driving technology is already on the road. Witness Tesla's semi-autonomous system, autopilot, which the carmaker added to its electric-powered sedans WHEN??? The system allows the vehicle to steer itself, change lanes, adjust speed and even find a parking space and parallel park.
