One Pedal Driving

True.
But still, if the car disables OPD to maximize regen, it means OPD is clearly not the most effective way to regen.

Or the thinking is flawed.

I never thought of that because speed reduction when releasing the throttle is absolutely the highest in OPD.

Because it's regenning more i.e. putting more back into the battery.
 
Remember, not using the brake often ,will result in Disks getting rusty and pitted. I got caught out on my last m.o.t ( advisory ). On my last E.V. This is around £ 660 for four disks, and more for pads are needed.
So using the brakes can be cost effective.
 
Yep.
I had them checked when it went in for the first service. They were fine.
In town, I still need to use the brakes quite regularly. Probably keeps them clean...

It really should'nt, the pads rest on disks all of the time very lightly, it should be enough to keep the surfaces polished and clean. My BMW i3 which I OPD all of the time has now got over 102,000 miles on the clock, still on the original brake pads and disks!

What make / model car and what mileage?

I cant agree with you there.
 
It was a Nisson Leaf 2nd generation, with 35,000 on the clock.
It was an advisory, and m.o.t. Fitter said, use the brakes more. Do a few fast hard braking runs often to polish the disks..the pads were only 50% used.

A Prius that I bought back in 2005 suffered from this. The brakes were hardly used. After a few years I had to have the disks skimmed.
 
There is no regen braking in reverse, so anytime you back out of a parking spot and brake, you scrub the disks a bit. If you are fortunate enough to always drive forward then finding a stretch of road where you can coast and put the car in Neutral will also do the trick, as there is no regen in neutral gear. I don’t think there is a “need” for any hard braking on occasion.
 
The hard braking suggestion is to ensure that the rear pads fully apply to the disks ... anecdotal info is that they are "unbalanced" and a light press only properly pushes half the pads onto the disks.

I'm sorry but I do not fully understand the process of one-pedal driving. How do you stop the car in an emergency? How do you switch "gears"?

You don't switch gears in an Mg4, drive, neutral and reverse still function on the dial, the brake pedal works fine, OPD is pretty much what you do all the time to drive, other than it brings you to a complete halt, rather than slow creep.
 
you apply auto hold in the setting, Then when you come to a stop..say traffic lights..you press hard on the brakes pedal and it will hold and not creep forward

If all brakes fail , you pull up the electric brake switch
