It is.
I am getting curious now, after reading all these posts. It is obvious that we think differently, but it is not exactly clear to me what is causing this difference. Since you are the first one to actually express your thinking about how you lift the accelerator pedal, I hope you don't mind that I pry into your brain a bit.
First I will describe my own thinking:
Before I test drove a Tesla for the very first time, I knew the concept of one pedal driving, but I had no idea what it would feel like. However, as soon as I tried it, my thoughts were "Okay, this is a function, which can brake the car with the accelerator pedal. So I will need to modulate my lifting of the accelerator pedal in the same way I would modulate my usage of the brake pedal."
And then it immediately became natural to do it that way.
(I had also been worried that this would not work very well with the TACC, when taking over manual control of speed after using TACC. Luckily, it turned out that TACC doesn't disable abruptly like in my other cars - it actually ramps down slowly, so I have plenty of time to catch it with the accelerator pedal and modulate the regen.)
And now back to you:
When reading your post, I get the impression that you think Tesla wants you to drive the car with a lot of regen. So when you lift the foot gradually to control your regen, you feel that you are not trusting the car.
Is this correctly understood? And how have you reached that conclusion?
