It's not about "play with some toys". It's about saving lives. Tens of thousands of people are killed by cars every year in the US alone. And the primary causes of those fatalities are the kinds of things most easily addressed by automation - lane drift. Running red lights and stop signs. Speeding. Driving too fast for conditions. Aggressive maneuvering leading to loss of control.
Drunken or distracted driving, by itself, doesn't kill. It leads to the behaviors that kill, like lane drift and speeding and running lights. These are all things that autonomous cars handle really well.
