Right now self-driving cars are a technical challenge. No amount of sensors and mapping can currently produce a 100 percent reliable self-driving car, but plenty of companies are working on it. When this technology does hit the market, the inevitable question is going to be "how much extra does it cost?"
Waymo, the Alphabet self-driving car division that was recently spun off from Google, is working on getting that cost as low as possible. According to a recent article from Bloomberg, the company has spent the last 12 months working on "scalability." The company's efforts have lead to a "90 percent" decrease in the cost of the LIDAR sensor, which is typically the most costly item in a self-driving car solution.
