Plaid vs LR MS batteries

[Candleflame]

You two are arguing separate points.

Driving slower will use less energy than driving faster. If targeting an average speed of X, maintaining that speed constantly rather than having variations above and below the average will be more efficient. Regenerative braking helps for those cases where you have no choice but to slow down, but if maintaining a constant speed is an option, that will always be more efficient.

(With EVs. With ICE cars there's another variable in that ICE motors are inherently more efficient at full load, partly due to less pumping loss... but that's not a factor here)

You are getting confused here. The argument was that frequent changes of speedlimits make cpnsumption worse. Which they dont. They improve consumption.

Not really, he was disagreeing with this statement I made, which is the same as what you are saying:
"Yes, the speed variation drains battery faster than maintaining a constant speed, since the regen is not 100% efficient."

Only if you vary your speee above the speed you would like to travel. But speed limit signs so the opposite.
