Like I implied somewhere above, that does not necessarily prove anything. Driving schools also teach a non-optimal method of setting side mirrros. Heck, my drving school back in the previous century taught me to parallel park in a way that wouldn't translate to any other car. They taught me to pass the exam in the particular car, not to drive.

This is an interesting argument, I'll definitely give it more thought. As I said, I haven't noticed it to be an issue in emergency situations so far. But possibly thing may different in other situations.


In the meantime, thanks to all of you who responded to my actual question - but it was also interesting to read all answers that were off topic.

By the way, looks like my position is not so uncommon:

Once again, I did not ask about that. I asked is there anything specific to the FRS/BRZ that would preclude using this technique in this car.

But reading all negative opinions on the technique itself was interesting too.

If you are 16 and use both feet on your driving test will they still pass you?


But seriously, even if you are lazy, how much MORE effort does it take to use both feet rather than just one. I don geddit.

You should set the side mirrors as far out as possible as long as the field of view barely overlaps with the inside mirror's field of view. This way you have maximum coverage and minimum blind spots. Of course, like with left-foot braking, you have to retrain your brain a bit, and use the inside mirror also to check the side lanes. But there is net advantage, and there was a SAE paper about that in 1995, yet only recently this knowledge slowly started to trickle into general knowledge.
@common knowledge Kinda like 2 cars traveling towards each other at 50mph do not equal a 100mph collision on either party as driving school teachers always told us. Thank you mythbusters!

LFB can be used to balance the car or set weight where you need it while keeping the RPM's up regardless of transmission, as well as simply for stop and go driving. Many top Autocrossers will LFB.
FINALLY someone who knows the right reason.

To answer the OP question, there is no difference. Its really similar on all cars.I used to do that when I first started driving in general and quickly stopped doing it, since I noticed that I was riding the brake pedals even tho it doesn't feel like it, and it jerks and stuff a lot. Plus it wouldn't be ideal in case of emergency, even tho some of the newer car has those safety tech that would somewhat (Wouldn't rely on it) stop the car from accel when both are pressed, on Toyota its called the "Smart Stop Technology (SST)".

Right?! Because clearly the issue is that he's buying a twin with an AT.


Just kidding @mdm trying to lighten the mood here.

So, I can tell you from personal experience, in certain situations the pedal dance is required. Case in point, diving into the toe of the boot at WGI where you have a handful of camber and you're heading into the hillside for more mechanical grip when the car decides (even though VSC/TC is "OFF") you're turning too much too fast and starts straightening you out towards the outer armco. Not a pleasant feeling.
Fast forward to the same corner after PD and the lap timer showing higher speeds, better sector times, and a confident warm-fuzzy in the driver.

As far as Ice Mode, I've experienced it only twice getting a little overzealous in AX with LFB, rotation, and trying to keep the RPM's up. Best guess, the problem compounds when turning because the wheels are naturally rotating at different speeds that the computer has to account for, add in the G's and yaw sensor inputs, sprinkle with throttle position sensor and poof... *BSOD*

Again, all the above is not street driving, just an example that the computer does not always know best.

Now back to your regularly scheduled thread...

We'll get right on that.

Right after we've finished researching the VTX trim level...

Body's tendency to move forward - body attempts to resist movement by pushing back with the feet.
What are you now pushing against? - The brake!
Brakes get applied harder, body resists motion harder pressing on the foot! MORE BRAKES!
It is called positive feedback, and any control system engineer knows THIS IS BAD!
So there's only one flaw with that theory. The seatbelts are designed to lock under braking so your body doesn't travel forward. Otherwise they wouldn't work.

As you are "two footed driving" down the road, please tell me what happens when you reach down and pull up on the seat adjustment lever in the front of the driver's seat.
Then report back.
This actually works fine. Your heel should be resting on the floor (since smaller muscle groups like the ankle are much faster to actuate than larger ones like your quads) and most seat rails have a decline to the slider mechanism. When you click the seat release you tighten your hamstring a little and you don't move at all, even while travelling down the road. Add to that, you can get slight braking simultaneously by rolling your heel forward.
