It's a persistent message: Self-driving cars are coming. Yet, before the roads are filled with cars steered entirely by computers, there’s much work to be done — especially when it comes to safety.
A grim reminder of that happened this past May when a man driving a Tesla became the first to die while using autopilot mode. He was watching a DVD when his car plowed into a tractor-trailer that was crossing its path.
That accident sent a message to the engineers who are developing this technology: get it right and make it safe.
