Technologies crossing over from one sector to the other is a phenomenon we are seeing more and more of recently. Car companies exchanging self driving and driver assistance technologies, and computer software companies have their tech included in a variety of cars.
Sometimes companies even stretch out to other domains and lend their tech to industries outside the automotive sector. That’s definitely the case with Ford’s “Lane-Keeping Bed”. The bed is inspired by Ford’s Lane-Keeping Aid which according to Ford:
monitors the road markings ahead and actively supports the driver to safely guide the vehicle back into the correct lane by “nudging” the steering wheel in the correct direction; this complements other camera‑based systems that help drivers avoid inadvertently straying out of their lane.

According to a press release issued by Ford Europe:
Just a prototype, the “Lane-Keeping Bed” is part of a series of Ford Interventions; applying automotive expertise to tackle everyday – or in this case, every night – problems.
