Who's used QNX in automotive for anything other than infotainment? A lot of people seem to think it's being used for vehicle control systems, but I've never been presented with a credible evidence of widespread use in production vehicles.
It's probable that QNX would underpin any future Mitsubishi Electric autonomous driving system, and more certain that it would underpin sensor integration etc. in future Mitsubishi car models.
But it's not being used there in current mainstream production.
It's certainly difficult to pick through the Blackberry QNX hype to see where it's actually headed outside of infotainment, lot's of fuzzy weasal phrasing:
BMW, Ford, GM, Honda, Mercedes-Benz, Toyota, and Volkswagen are all users of QNX’s safety-certified versions, which I would assume means more than just infotainment.
