I'm not a fan of moving key controls onto touch screens, as is the current trend, because it's bloody unsafe! So moving towards gesture controls seems bonkers to me. Style over function. I think they, the car designers, should be concentrating their efforts on finding ways to operate all essential controls from the steering wheel. Surely it's much safer to keep your eyes ahead and learn how to navigate the key controls whilst holding the steering wheel. If they put their minds to it you could have an F1 style steering wheel in which the driver could access 'almost' anything without needing to look across to a sodding touch screen. Which is both dangerous and clunky whilst on the move.
