Sounds like the author is waxing lyrical about regenerative braking? A bit breathless and certainly veering into marketing (rather than analysis) territory.
If you've driven a heavy vehicle up and down steep stuff, regenerative braking is super nice. shifting into 3rd or 2nd is not the same. A compression brake is kind of ok.
This is exactly my point. Establishing that regenerative braking is "especially helpful" for a particular driving context feels like a conclusion one could not reach during a test drive.
More likely that the author got some talking points and maybe even data from the fine folks at Rivian.
however, automatically engaging regenerative breaking is especially helpful for mimicking a manual transmission (without freewheel/overdrive). It's a desirable characteristic for sporty driving styles.
my favorite piece of BS is "they've flipped the script!" I hope not, people already know what they want a pickup to do: haul their stuff around. They don't want their stuff hauling their pickup around, for example.
Except it mimicks downshifting a transmission where you can have different gear ratios at each wheel, dynamically! It's the perfect application of this tech.
Yes, it's a puff piece, but that doesn't mean there's not truth behind it.
