Mercedes-Benz studied the brain waves of sleepy people and matched it up with some lethargic wheel-turning skills. Apparently, the resulting combo is a sedan that has the brains to tell if you're in la-la-land. The newly developed Attention Assist uses sensors on the wheel to check your attention level and if it feels like you're dozing off, it'll do stuff. It'll sound off an alarm and display a little icon that pushes you to take a cup or two, which is cute. But one has to wonder, what if you are a bad driver? And what if your wheel-steering skills are pretty defective as it is? 

Thankfully it's only going to show up on the Mercedes E-Class.
