According to ALPS, a wheel trackpad is easier to use (and safer, too) as well as more convenient than pressing separate buttons on the car’s steering wheel, where you swipe your way through radio channels, adjusting the volume, control your navigation system and who knows – play Angry Birds? I guess the last bit can be ruled out due to the hazard it poses, but ALPS claims it can also work with letter recognition as well.
Currently, the Audi A8 relies on such technology albeit not on the wheel. I wonder how much more a car’s price is increased with this spanking new wheel trackpad in place.
