Unintended Acceleration - really happens

[LL - NY]

As a left foot braker in competition (4 regional Solo championships
in an NA GTi) I also disagree that in trained or experienced hands that
LFB be banned or prevented. The Drive-by-wire system in VW's prevents
it (I was startled when I was trying to brake torque my Mom's Passat
to try to get it into traffic, it went into limp mode just when I needed
power most!), so I guess DeWitt's prayers have been answered to some
degree. As for LFB failing to keep an engine on boost when the revs drop
to low, it's true, the Saabaru can end up lugging, in spite of LFB in
Solo competition, pretty well once when revs drop below about 2600 to 2800
RPM. I've become somewhat proficient in downshifting the thing into first at
speed without shock. Never had to do that before on any other car I've
competed in.
