Looks to me like a solution looking for a problem. I've driven millions of kilometres and never ever had an issue with "unintended acceleration" - even when driving automatics, where I use both feet.
It's a skill easily learnt (forklift drivers use both feet all the time), although some people can't seem to transition from a manual to an auto and not apply clutch level pressures to the brake, resulting in unintended crash stops. :-)
I reckon people should be properly taught and learn to drive and not be given some of these silly electronic nannies to save their inept skins, although such facilities as TCS, DSC and ABS I don't believe fall into quite the same category as various lockouts such as this, and auto headlights and rain sensing wipers.
I know where the wiper switch is thanks, and am perfectly capable of determining when and how I want the screen washed. I might choose to leave it because of dust on it and I don't want a scratched screen. I never saw a system make that kind of decision before.
