Ignorance is bliss—but try telling that to the auto industry. According to a connected cars and autonomous vehicles survey published by the firm of Foley and Lardner in 2017, more than 70 million connected cars will be driving the roads come 2023.

Connected cars utilize an array of sensors. They know how much gas you’re using, where you stop on the way to work each day or if you’re prone to breaking the speed limit getting there. It’s a treasure trove of information that can be incredibly useful to auto manufacturers looking to develop the next generation of artificial intelligence and autonomous vehicles.
