That drive by wire is going to kill Toyota.
Somethings going on in the electronics, emi or a software issue.

IMO, there's nothing fundamentally wrong with the concept of electronic throttles. They offer many advantages, including custom profiling of tip-in characteristics, ease of integration into cruise control, ease of calibration, more options on where the TB's can be placed, elimination of issues with cable or linkage friction. The control system can also be engineered to be fail-safe in nature, and you can integrate a lot of safety features (e.g. automatic throttle cut on heavy braking) that would be difficult to do with a mechanical linkage.

As for mechanical linkages, they're subject to jamming open, just like electronic linkages.

The issue here isn't electronic or mechanical, it's doing good engineering. Toyota blew it when they didn't initially incorporate a throttle cut under braking into their system, just like most other manufacturers. They're quietly adding this to their system when cars come in for the pedal/mat fix.
