People not paying attention or multitasking instead of paying attention is a wider problem than just drivers at stoplights, I'm afraid. They're talking about cars in 10 years driving themselves, so the "drivers" can do more important stuff like update their Facebook page or whatever.
Cars today have automatic everything, radar sensors, back-up cameras and computer screens. Whatever happened to just paying attention and driving your damned car with your brain fully engaged?
OK, rant over.
