It took a decade or so of driving and killing for the first laws against drunk driving to be passed (1910). It took another 20 years (1930s) to really work out what "inebriated" meant in a legal context and set definite limits. Another 30-40 years passed before the "inebriated" limit got refined enough to have its greatest impact (impaired vs. stumbling drunk). Please pass the law, then in 10 years we can all laugh about how people used to actually drive a car while talking on a cell phone as if that was acceptable! (Although I hope not to be driving my own car in 10 years. That's robot work. I'll be reading a book or napping until the robot fires the "human attention required" alarm.)
