The next frontier in digital advertising may be your car’s windshield.

Automakers, technology companies and glass manufacturers are teaming up to turn the display that graces the front of an iPhone into the windshield of a car — one that can show ads, directions and vehicle information to the person behind the wheel.

The advent of connected cars is creating a new sales battleground, and using a vehicle’s windshield may be the next way to pitch more products and services to consumers. McKinsey & Co. estimates that mobile and data-driven services in autos will generate $1.5 trillion by 2030. At least part of that will be spent projecting information to drivers and passengers right before their eyes.

“When you think of a person driving and what your needs are when you’re on a typical trip, it’s food, it’s fuel and it’s rest stops,” said John Butler, a Bloomberg Intelligence analyst. “Owning the inside of the car is critical, it’s really where the money is made. The real value is locked up in the ad opportunity.”
