27: Drowsiness Detector
Self-driving cars have become the next hot thing in the automotive industry. These cars will revolutionize a segment and allow people to drive who might not have been able to before. These cars will also change the way we drive across the country and take long driving trips (via Are You Selling).
One of the things that has been highly publicized when it comes to self-driving cars is that the driver can fall asleep at the wheel. This has been happening a lot with Tesla models, and it represents a dangerous problem. Luckily, automakers have been quick to adapt new technology that lets the car know when the driver has fallen asleep.
