A quarter of America’s major metropolitan roads have stretches in substandard condition, and drivers pay the consequences—potholes alone cost car owners an average of $335 a year in tires, repair and maintenance.

The process can take as little as two minutes, but the fix is only temporary.
Any attempt to segue into this post with a clever lead is likely to fall flat, so in the interest of skipping the cliches: a new study out of University of Colorado Denver and Montana State University shows that legalizing medical marijuana sales in various states over the past two decades has led to a nearly 10 percent drop in traffic fatalities.

Of course, when under the influence of alcohol the tendency is to think you are a genius (also: good looking, charming, interesting, a qualified referee, good at billiards). So a new technology incubating with the backing of the U.S.
