The potential complications are enormous, but so might be the benefits.
Driverless cars and trucks—or autonomous vehicles (AV)—offer a tantalizing promise of safer and unclogged roadways. In 2017, 37,150 people died in accidents on America’s roads, reports the National Highway Traffic Safety Administration, up sharply from 32,479 in 2011, and far worse per capita than anywhere else in the Western world. And the United States has ten of the 25 most congested cities globally, according to the Inrix transportation intelligence group. Cars that drive themselves could reduce crashes to a small fraction of today’s totals, while moving people about more efficiently, in larger groups and at faster speeds.
