Anyone with halfway decent strength and balance can left foot brake, but it takes concentration/focus/attention/effort that detracts from the other stuff you're doing on track (such as staying on track ...)

I used to reserve left foot braking (LFB?) for only those turns where it was really compulsory (eg. T2 at Laguna) but in the 996 GT3, the car pretty much told me I needed to get with the program and keep the pressure on the nose of the car while transitioning to power.

I find LFB to be hard to explain, but relatively easy to learn, then it's just a matter of practice and repetition with attention to the balance of the car. An SUV makes for a great teaching car. Even in a straight line at a walking pace, just feel the brake on and off, then balance that with the throttle so that you're feeding in power without gaining or losing speed and you can feel the car "compress."

Porsche limits the amount of time brake and throttle can be applied simultaneously. This is said to prevent the "panic" situation where an incompetent driver will push their right foot onto the brake and inadvertently depress the throttle -- this can lead to some of those YouTube videos of cars lurching into shop fronts, etc. -- but the time required to effectively transition is only the time taken to move from wide open throttle to full brakes, then from the peak braking and steering input at the apex to zero brake as the car tracks out and away from the apex. If anything the brake-throttle helps as a reminder when one becomes lazy (and slow) with the left foot.

PDK understands left foot braking, even in the 997.2 cars, it's smooth and doesn't make mistakes. I have to imagine the numerous computers all futzing around with the 991 GT3 will have a game plan and to drive the car as quickly as possible, you'll simply have to adapt to that plan. I'm not too happy about that approach (it's sort of like getting a good score on a video game, you're no longer exercising a raw skill so much as learning to pass a multiple choice test by process of elimination ... that's not the raw learning of a skill, that's the adaptation to a virtual environment created by software people.)

Perhaps this has been deactivated in new gt3. It wasn't in my RS.
