The headlights flash information such as speed limits, navigation-based turn arrows, and road conditions, as well as a warning about an upcoming roundabout. Another possibility is to see the headlights illuminate a path to ensure cyclists are passed safely.
The technology might even assist drivers in identifying the correct parking line to follow, or highlight the vehicle's width to help them identify whether or not they can fit in a gap or parking space. When stopped, the system might create a virtual crosswalk for pedestrians in situations where existing painted road markings are faded.
Ford's suggestion might be beneficial in certain situations, but it may also open a whole new front door to the Blue Oval.
It is easy to see how this feature might be beneficial to drivers on a dark country backroad with no other cars around. Move to a busy freeway with other cars also using the same technology and you are suddenly in the midst of what appears to be a very distracting environment.
Imagine a nightmare scenario in which someone hacks the system to project the wrong turn arrows. You're going along and see an arrow indicating the road is about to turn left when in reality the route unexpectedly veers to the right.
The drivers who project the headlights may have to comply with different statutory requirements in different industries.
Ford will not be the first to introduce this sort of technology to the market. Mercedes already offers a similar technology called Digital Light on select models like the S Class.
