CGX car nut:

The brake regeneration question is a very interesting issue.  Many EV enthusiasts have criticized Audi and Porsche for not enabling one pedal driving; however, there was a writer for Car Magazine that almost immediately noted the advantages of the Volkswagen Group approach.  He had driven a Jaguar i-Pace across the continent and remarked the one-pedal driving with strong liftoff brake regeneration was tiring over that long trip.  

 

Because that's the Tesla way. Doesn't mean it's the correct way or incorrect way, but they are all used to the monopoly car in the segment doing it hence comparing everything to that.

VAG designed theirs to act like a normal car. In normal cars when one lift off the throttle, the car doesn't suddenly slow down, it keep most of the momentum and keep rolling more or less the same speed. It is what every car driver in the world are used to, and to get normal car drivers to convert to electric, it's best to keep things normal. 

Another thing is VAG think energy conservation first. Converting kinetic energy will have loses, it's not  a 100% conversion, so why waste perfectly good energy when it's perfectly fine to take advantage of that energy to keep the car going?

The slight lift off regeneration selections are good enough to hold the car speed constant going down hills, so one doesn't need to ride the brakes. 

Another thing is, Tesla doesn't have the know-hows to blend regen braking with physical braking, they are forced to design their cars like they are, the moment the driver touches the brakes the regen is off and physical brakes takes over.

VAG, via Porsche, have years of experience tuning the interaction between physical brakes and regenerative brakes, seriously, no one is remotely close, so why not show case their leadership in that segment? Also why Jaguar can't do blended braking and had to resort to using lift off regen.
