Unintended acceleration

To comment on Brett's point:  He's right.  Even a mundane, average, cheap
car today has roughly 1200 HP available in braking force.

Unfortunately, some drive-by-wire systems do pull throttle under braking or
when yaw is detected.  Which makes left-foot-braking, threshold braking at
turn in, and other more advanced techniques impossible to do smoothly.
Probably good safety for the average driver, but as an instructor....  I
hate that!

At least Porsche and GM with the Corvettes tune this behavior correctly.
Allowing quite a lot of driver latitude before it shuts down the fun and
protects us from ourselves.
