Okay, this article is good, but is missing some points.<p>1. Left-foot braking has always been a popular method of controlling a car in racing. The trade off of extra wear for extra control is worth it in competetion. Tech has now made it so the wear can be avoided by using digital logic, rather than its mechanical analog. On snowy days, or in gravel, I often use my brake and gas at the same time to help position the cars inertia in relation to its cg/moment and get a better heading and balance on the exiting end of the curve. Which is to say the car shifts its weight to be less likely to slide in a way I do not anticipate. Common in rally, less so on the streets. However many older people I talk to know the technique, while those under 40 seem not to. Perhaps it is a function of having astoundingly better traction now.<p>2. Having done lots of left foot braking, it is not as percise. You use your 'free foot' in an automatic to brace your body to give a solid refrence point for control inputs. Using both feet puts this all on your seat, and frankly they all slide and deform if remotely comfortable. You can mitigate by anchoring your heels and modulating pedals with toes, but some find this unnatural or uncomfortable in some configurations.<p>3. It can be learned, but it takes quite a while to get used to it. Took me at least a year before I was free of the jerky difference between feet. I think training new drivers would have the largest effect. If learned from the start it should be natural, just as a manual transmission is to me.
