John Dvorak at Marketwatch:

In a Prius, as well as many computer-controlled Toyotas, the accelerator pedal is more like a volume-control knob than anything else. In the olden days when you stepped on the pedal, it would be directly connected to, say, a carburetor, and open a valve mechanically as you pushed down.

This is now passé, as this activity is done electronically on the most modern cars by network signaling.

A good article explaining how auto makers went from hardware to software and may have put us all into hot water. Here’s hoping not.
