2021 E-Class will use capacitive sensing to check for hands on the wheel
Mercedes-Benz has just unveiled the 2021 E-Class, and like many of its German luxury siblings, it will come equipped with the company’s latest driver-assistance features. But the new E-Class also changes how the car registers whether the driver is paying attention while using those features, as Mercedes-Benz is introducing a new wheel with capacitive sensing.

The problem with this method is that it’s often hard to get the balance right of how much movement needs to be measured to say for sure that a hand is on the wheel.
