OK, as I promised I put up the left foot braking idea up as a thread in the driver education section of my Ferrari web site.
Although it died here, (and I could not find it to add this), it has lived for at least a couple of weeks over there (40 posts now).
The concensus is just about 20 to 1 that left foot braking is perfectly acceptable with an automatic on the public road - IF the driver makes the effort to learn how to do it well. ((does not drag brakes, over use brakes, etc.))
Interestingly, over a dozen posters there have the paddle shift manu-matics in their cars and race them in amateur events. All say they have started using LFB on the track and have shifted to this on the road to keep in practice. Several are like me - in that they have always used left foot for braking with automatics as long as they have been driving cars.
One person (who claims to know) says that about half or more of the Formula One drivers today use left foot braking - F1 cars no longer have a foot clutch pedal. Many current racing drivers got started in Karts, almost all of which all have left foot braking. All the racers claim that they can lap faster with LFB, and that in certain places both brake and accelerator are needed together to balance the car.
Note that I am not saying everybody here should do this - but at least for the hard-core Ferrari people it is a pretty much accepted practice.
