Driving while drunk is treated very seriously these days - very expensive and very disruptive to your life. But driving while drunk is no more dangerous than driving while sleepy, driving while talking, or driving while distracted, and they are all just as voluntary as driving while drunk. We wrongly accept 40,000 people killed on the road each year just like we accept 500,000 per year killed by cancer. The focus on drunk driving is important, but too narrow.
