All that said, why would you want to drive around in B? There's a lot of economy to be had in coasting.
It saves on brakes and increases your range. I live in a hilly area, so that might make a difference. My daughter drives a few miles down to her school and arrives with more range than she left with. I also find one pedal driving to be much more enjoyable.
I had the same experience with Tesla sales people not knowing what they were talking about. I would imagine that the misinformation is significantly worse at an ice car dealership.
The e-Golf will use the regex brake when you press the brake pedal in D mode, and will only engage the friction brakes once the braking force requested is stronger than the regen brake can offer (or if there's wheel slip)
B mode only has the effect of making the car apply regenerative braking when you lift your foot off the pedal (i.e. the regen brake is ON, unless you're pushing the 'gas' pedal). The brake pedal responds the same way in B and D mode. The only way to really wear down the brake pads on the e-Golf is lots and lots of hard stops. If your "charge" needle on the dash is lower than ~90%, its likely that you're only using regen, even in D mode!
Range increase is a complex topic here, for certain driving conditions B mode will increase range, for other conditions it will actually rob you of range. The reason is that regenerative braking isn't 100% efficient, so you will always regenerate less energy than you spent to accelerate. As such, the "perfect" efficiency would be to accelerate with precisely enough energy that you get up to a speed, take your foot off the pedals and just coast to a stop, exactly where you needed to stop, without ever touching the brake pedal so as not to lose any energy to friction or to heat through regeneration. This is, of course, completely unrealistic!
If you're able to coast in B mode without inadvertently speeding up and then slowing back down from minor foot pedal motions, you'll find that you can achieve excellent efficiency. I also find that in stop start traffic, coasting slowly while traffic is creeping tends to save me energy vs the more 'stop start' style that the one-pedal driving lends itself to in that situation.
With all that said, one pedal driving is very enjoyable, and your own personal driving style may be completely different to mine. There's no wrong way to drive the car! I often use one-pedal driving because for 95% of my driving I could be getting utterly terrible range and still never run into issues.
Regarding your daughter arriving at school with more range than she left with, unless the trip is significantly downhill the whole way its more likely that the guess-o-meter is recalculating range from driving efficiently. compared with actually ending up with more energy in the battery than it started with.
sorry for the wall of text! Hopefully this helps with some info, though. The dealerships are worse than clueless.
