Right foot and FSD

I can 100% relate. Since FSD is not *really* FSD, for cars like my 2020/21 Model X, you have to be ready to take control instantly. So hard to relax. I try to beep my right foot close to the brake. Not really comfortable.

I put both feet flat on the floor.

It’s situational for me. I have both feet flat on the floor when cruising along. If I were in control I’d still have to move my foot from the accelerator pedal to the brake pedal anyway. It’s the same thing flat on the floor, have to move my foot to stop the car anyway. I rest my foot on the brake in certain situations, like when I need to make a left with incoming traffic or parked cars blocking my view because if I can’t see then chances are the car probably can’t see much more either. I also rest my foot on the brake when doing a U-turn (very common to do in California) or when making any turn really (into a parking lot or parking space). I rest my foot on the accelerator when I’m anticipating a merge or lane change coming up that I may have to assist in a little speed boost to make it happen quicker/better. Edit: I mean do you have to hover your foot? Can you just rest it on the pedal? I don’t hover it, I rest it on the pedal. It’s comfortable enough.

For the longest time (more than a year) I drove with my foot set just over the brake ready to stop. It got tired. Recently I've gotten more comfortable with the idea of taking over with the wheel, which is almost always how I intervene when needed anyway. So now I usually keep my foot resting near the pedals.

Try doing it on a 450 mile trip. You'll find comfy at some point.

My answer (the answer) depends on the vehicle and whether it has HW4 or HW3. In my previous HW3 Model 3 I kept my right foot as relaxed as possible hoovering over the throttle pedal. In my present HW4 Model Y I prefer to keep my right foot flat on the floor due to the more upright seating position.

Yeah, this is ideally where I want to be. Hopefully I’ll get there with more time and miles with FSD.

Nice, I tried using the wheel as the default exit from FSD, throughout my drive today. With regen braking it works so well.

So what happens when you take over using steering wheel? Does it automatically hard brake or it’s just like you let go of pedal so slow brake?

It does not hard brake, it kicks in the regenerative braking as if you just let off the accelerator which is essentially what you did. Which I'll say does stop pretty quickly, but is NOT an emergency stop. I'm sure it slows my hard braking response by a fraction of a second if i had to, but i can't think of a single intervention I've had to take that was for hard braking (not to say they dont exist, I've seen the videos.) Most of mine are lane selection/navigational or avoiding potholes.

If you used cruise control on previous vehicles, where did you place your right foot. I always placed mine flat near the pedals and do the same with FSD.

On the floor or over the accelerator to help nudge FSD sometimes to go 😁

I’m a veteran of the “sudden braking” versions of AP/FSD, so I keep my foot hovering over the go pedal.   Even now, most of the time that I want to correct FSD, it’s to nudge the accelerator to leave a bit more room for the person behind me as I change lanes.

Funny you mention this. I had the same exact thought just recently. Would nice if there was a slimmer pedal option with a rest on the right side for us fsders.

On my '26 Y, I keep my feet flat on the floor, on my '22 3, they will only be flat on the highway/state road. I'm not comfortable with turns on my '22 still for some reason lol

It depends on where it's driving. Freeway? Resting on the accelerator, no added pressure. Allows me to maintain speed if there's a sudden deceleration, or it's just acting dumb maintaining speed. Surface streets, lots of traffic - ready position over the brake pedal. Switching to accelerator whenever prudent.
