Mercedes isn't new to experimenting with augmented reality, and at MWC 2018 the company showed off its latest creation with that technology. The "Vehicle Lens" app is exactly what it sounds like: It uses a smartphone to give you an AR view of a car or truck, showing vital information as you move around and point the camera at different parts of your ride. If you have it facing the wheels, for example, you see details about tire pressure. That will come in handy before taking a trip. In addition to that, Vehicle Lens can display engine info like mileage and coolant levels, how much fuel there is and personal info about drivers -- including if they've been driving for too long.
