aerodynamics, and, accomodating a raked windscreen has something to say too, making an eye level dash less viable/reachable anyway, thus the protuberance of the touch screen,
the integration and cost/reliability saving, of not having banks of mechanical buttons an added bonus.
But on the flip side legislation/research on the the tablet safety aspects, seems remisce, NHTSA guidelines (linked before) not enforced
-eg size/responsiveness of touch screen button, rapidity of feedback, haptics; the wild west ?
manufactuers must, now, have the telemetry to record if the touchscren was being used at the time of an accident, and, there does seem a discontinuity of thinking versus handheld devices.
