I&#x27;m finding it very difficult to dig up actual statistics on what percentage of accidents each year are caused by drunk drivers, most likely because I suspect the percentage is extremely low. The nearest I could find was a statistic that about 7% of all vehicle accidents involved an alcohol impaired operator (<a href="http:&#x2F;&#x2F;www.encyclopedia.com&#x2F;doc&#x2F;1G2-3403100014.html" rel="nofollow">http:&#x2F;&#x2F;www.encyclopedia.com&#x2F;doc&#x2F;1G2-3403100014.html</a>).<p>That said, why do you think impaired drivers are the biggest danger on the road? I firmly believe it is simply bad, irresponsible, untrained drivers caused by 1) the ease of obtaining a driver&#x27;s license, 2) the lack of expense overall in owning and driving a car and 3) the very low standard of acceptable driving that&#x27;s the most troublesome. It&#x27;s going to be easy to throw a drunk in an autonomous vehicle and ship them home. It&#x27;s going to be exponentially more difficult to provide access to autonomous vehicles to the general population.
