1. I not only went back and re-read your post, I'll paste the relevant portion here:
"1. Regenerative braking can only be used on driven wheels;"
The vast majority of cars are driven by two out of their four wheels. Therefore by referencing "driven wheels", you are stating 2 out of 4 wheels, which maybe you'll agree is 50%?

2. I do not have reading comprehension problems. Perhaps you have driving comprehension problems? You are making an incorrect assumption that braking only the front wheels creates "a high risk of spinning" (your words) when going down hills.

Have you ever driven a motorcycle, on which the front and rear brakes can be controlled independently? I have many hours driving motorcycles and in my experience, in all but panic or high-performance stops the vehicle can be stopped safely with either brake regardless of gradient. I have also driven cars with non-functional rear brakes with little difficulty, even on hills.

You'll note in that last statement I did exclude two circumstances. In a panic stop, I would expect the vehicle's systems to do whatever is necessary to provide maximum stopping power, which of course would mean braking all 4 wheels which would mean less energy captured by regeneration. And in performance-driving situations, energy efficiency is not the top priority and it's only sensible that additional energy loss would be tolerated in the name of getting max performance, just as when accelerating. But panic stops and max performance do not represent the majority of situations encountered by the majority of drivers.
