The Potential Human Cost of Waiting For Perfect Self-Driving Cars

As companies like Waymo ramp up tests of their self-driving cars in Phoenix, state and federal officials continue to debate when “good” will be “good enough.”

Now, a report from the RAND Corporation says pumping our brakes and holding out for the perfect automated car is a mistake.

Worth Doing Right: How Climate Change Could Throw a Wrench Into Road repairs

Repairing with the wrong materials for shifting climates could be a road to nowhere, like this spot in the Suffolk village of Covehithe. Picture by Timothyansell123.

The American Society of Civil Engineers has given America’s roads a D rating. But a recent study shows that trying to raise that grade without accounting for climate change could put the country’s roadways at risk.
