I bet it works well, and can believe it takes less time, but it doesn't fix the problem of drivers distraction completely. HUD's and voice control does it better I guess. Also, soon the market will change dramatically with driverless cars...
Agreed. The only thing that will solve driver distraction entirely is to remove the need for drivers to pay attention at all. However, we're still a good 5 years away from true self-driving cars being available, and longer than that for mass-market versions to really gain traction. This is something that could be available today.
I understand you and agree it could be available today. The idea is not bad in general, but what are the chances to convince any car company to implement it? Minimal.
