Curious why some do not use 1 pedal driving.

I have seen in some threads that some don't use the 1 pedal driving and I wonder why. I took a 60 mile drive yesterday and only had to use my breaks twice. At the rate I will likely never have to do a brake job. Plus a little energy recovered.

For me it's because I hate it. I've trained my brain for 30 years to use two pedals and use the momentum of the vehicle to save fuel/energy. I do not want to try and untrain my brain at this point. 1PD is WAYYY too aggressive with regen braking and it's just annoying to have to keep applying pedal pressure to coast down to a stop sign, red light, or down a hill on a rural road. I honestly don't think it saves much energy because what you get back in regen you spend applying throttle at times you normally wouldn't.

Not saying it doesn't use regen, but it doesn't ONLY use regen, so can't be as efficient as 1P drive.

When slowing the same amount it uses the same amount of regen. The difference is you CAN slow harder with the brake pedal.

I have monitored brake line pressure as well and using the brake pedal has ZERO pressure in the brake line up until you exceed the max the battery can take. No pressure in the brake lines, no use of the mechanical brakes.

This is a "feature" being discussed around the web right now. It's a comfort thing that is unnecessary.

100% disagree. It is not possible to be as precise in 1pd as 2pd. The delay in response due to the throttle dead zone, as well as the need to switch from gas pedal to brake pedal, results in a lag and increased difficulty in precise positioning.

Do you 2P drive with 2 feet??

Incorrect. Regardless if you use 1P or 2P, once the vehicle speed gets slow enough, it MUST fade in friction brakes. The reason is there simply is not enough momentum to be able to create much electricity from the motors when they are acting as a generator. As I said, I have watched the brake system pressure in both 1P and 2P mode. In similar braking condition, the brake system pressure is as identical as can be seen with CarScanner.

No. And to creep forward you only need one, the one on the brake.

You can creep forward with 1P drive. It isn't hard and I do it at stop signs and red lights on right turns all the time. More efficient to not have to move your foot to break.
