Finally! A friend was an in-house reseacher at some car manufacturer, whose job is to usability tests car prototypes, including in real traffic.<p>She was telling me about one study in particular to try a new touch screen built behind the handbrake, pretty much at 5 o'clock behind the driver. I'm sure she's not the only one sharing usability reports about how dangerous touchscreens are while driving, but marketing needed to advertise one more screen than the competition... This was 5 years ago. Took them a while to pivot, but i guess better late than never.
