This Tesla argument is completely irrelevant. One company's managing to design a good touchscreen interface doesn't mean any other touchscreen is well-designed.

Rich people who can afford Teslas may have a safe driving experience in isolation but the vast majority (who can't afford a Tesla) are stuck with a poorly designed touch interface, making road conditions less safe for everyone (even Tesla drivers with their perfect touch interfaces), through no fault of their own.

Bring back the knobs.
