I don't know if you were in on the other thread, but do you realize that every time you come off the gas to coast in B your brake light comes on? Even if you are driving at speed. You are probably driving people behind you nuts in B all the time. I love driving in B but I significantly cut back my use of it because I think it's important to have good road manners.
Psycho.... the e-Golf has a 1 speed transmission. Over revving the motor is impossible.
And, to quote you.... you don't know how he drives...
Overcharging the battery in regen mode, if battery is near full charge, might be possible, and cause loss of regenerative braking. Over revving the electric motor is impossible with a 1 speed transmission, the car is capable of 90 mph aprox. So is the motor and the transmission.
I've lost regenerative braking once, on a 100F hot day going down the Conejo grade on the 101 freeway, in CA, with gauge at about 5/8 showing. I think it's about 1200 feet or so lost at a 6 or 7% grade. I attribute it to the battery getting too hot from forced regenerative braking. I was in D3 at the time, holding 60 mph.
It's a VW "Safety Feature" with a passively cooled battery, instead of liquid cooled. One of it's cost /performance benefits to keep e-Golfs affordable, vs the extra cost and pricing of an actively cooled LiPo battery.
A VW "compliance" car is going to reach design limitations rather quickly, with the "Fast and Furious" style of driver.
