The newton comes to mind, a hand held touch screen device that was launched a decade before the palm pilot fulfilling no use and being extremely expensive. Flash forward 30 years and everyone has a touch screen mobile computer in their pocket, but the newton was a complete failure.
Sounds like your daughter needs to actually learn how to drive. I made scary mistakes when I was learning but the key was I learned to not make those mistakes. Take the phone out of the equation and let her learn the roads where she’s driving. Teach her to pay attention to her mirrors, what other drivers are doing (and not doing) and anticipate moronic behavior from other motorists.
