And for the record, the idea that people of any group are plug-n-play replaceable is NOT an MBA notion but rather the modern woke-ism rearing its head.

The MBA curriculum may not address it directly but is very much about recognizing, exploiting and rewarding MERIT, not group identity.

Of course, it's been a while since I sat in a desk. But then and now, in any profession, there are good practitioners and there are buffoons. Just because a buffoon managed to somehow get an MBA, and get hired, doesn't mean all MBAs are that way. Sadly it seems the noisy buffoons are the ones everyone notices.

I don't follow how you inferred from your previous comment.
How is it "defective"?
A single-pedal speed control with regenerative braking can certainly recover a fair amount of the kinetic energy when slowing down.
Not as efficient as coasting, but I wouldn't go so far as calling it defective, although I wouldn't want one.

Evidently "W" has been much more fortunate than I have been over their career. My experiences have been different. Some folks have all of the good luck, others are not so fortunate. I have been fortunate to work with several really great engineers, and be involved in a lot of really great projects. And suffered the attitudes of some really miserable individuals who

That was @MisterBill2 not me.
INDEED!! consider how difficult it would be in traffic with those many unskilled drivers, if they had to exactly hold a speed, and whenever they backed off a tiny bit the car went into a braking mode, instead of just coasting. Traffic would be even more "Herky-Jerky". Like "THE LOOP" in Chicago with heavy traffic. With a single pedal coasting down to a slightly slower speed would be impossible.

Sorry, I got confused (which I easily am) when you answered my reply to him.

Not at all.
The regenerative braking is not all or nothing, it is proportional to the degree of reduction the the accelerator position below the no forward power point, so it's not difficult to slow down at the rate desired.

I would imagine Regenerative braking might feel a lot like down shifting, which I mastered while driving my Roadrunner.

Still need a proper brake and such.

As for downshifting to decelerate, consider the relative cost of clutch replacement versus the cost of brake shoe/pad replacement. I can replace all of my brake pads several times for the cost of one clutch replacement. And, of course, regenerative braking is not effective below some speed, and it will not keep the car stopped if there is any slope on the road at all.
And why think that those poor unskilled drivers will be able to handle a one-pedal scheme any better than the present system????

Of course.
That's why all EVs also have conventional friction brakes.

Apparently some of us are more optimistic about things than you are......
There may be a few that can't handle it, but I think the average driver can.
