What Crazy Dash Cam Videos Teach Us About Self-Driving Cars

THE FIRST SELF-DRIVING CARS are expected to hit showrooms within five years. Their autonomous capabilities will be largely limited to highways, where there aren’t things like pedestrians and cyclists to deal with, and you won’t fully cede control. As long as the road is clear, the car’s in charge. But when all that computing power senses trouble, like construction or rough weather, it will have you take the wheel.

The problem is, that switch will not—because it cannot—happen immediately.

The primary benefit of autonomous technology is to increase safety and decrease congestion. A secondary upside to letting the car do the driving is letting you can focus on crafting pithy tweets, texting, or do anything else you’d rather be doing. And while any rules the feds concoct likely will prohibit catching Zs behind the wheel, there’s no arguing that someone won’t try it.

Audi’s testing has shown it takes an average of 3 to 7 seconds—and as long as 10—for a driver to snap to attention and take control, even when prompted by flashing lights and verbal warnings. This means engineers must ensure an autonomous Audi can handle any situation for at least that long. This is not insignificant, because a lot can happen in 10 seconds, especially when a vehicle is moving more than 100 feet per second.

[…]

The point is, the world’s highways are a crazy, unpredictable place where anything can happen. And they don’t even have the pedestrians and cyclists and buses and taxis and delivery vans and countless other things that make autonomous driving in an urban setting so tricky. So how do you prepare for every situation imaginable?
