Driving in rain is no problem for this self-driving car

Mashable 

If you've ever wondered how a self-driving car might handle bad weather, inconsistent traffic signals and unpredictable human drivers, you may have your answer. Drive.ai, the self-driving car startup that adds autonomous car-to-human communication through visual cues, just took one of its retrofitted self-driving cars on the kind of road trip that can prove particularly challenging for people and autonomous vehicles.

Self-driving cars in that part of the U.S. are not unusual, but as the car drives, the sun sets and the rain starts. Soon it's pouring and visibility of street signs and, especially, lane markings all but disappear.
