Does anyone use the 'B' mode

Yes, in all automatic you can switch from D to B, N, but not R and P as long as you don't touch the brake.  Just like 321 in regular 5 or 4 speed transmissions.   Just don't touch that shift when touching brakes because you can accidentally shift to R or worse P.  I did it once when braking and put P to early before the car completely stop. I heard loud  creaking sound. I am sure I caused some wear on the pawl but fortunately was fine 40k miles later.

Once I was driving slow looking for an address in the dark and instead of pressing the hazard button I did press the P button and the car stopped suddenly, what a surprise 🤣, no damage to transmission or my head but wasn’t a pleasant experience., done the same at higher speed instead of EV I did press P again but nothing happened only beep and message on the dash, maybe went into neutral too but can’t remember now. The cars are kind of made safe these days.

TBH I almost never use B-mode. I think if I was going down hill that was so long it fully charged the traction Battery, it'd be useful, but normally I prefer to brake just enough that the regen bar hits the maximum 3 blocks, but the friction brakes stay off. That way I can harvest as much energy from braking as I can.

I don't know if this is the case with all the Toyota hybrids, but on my Mk4 Yaris the B-mode does almost no regen and wastes all the energy that could have been captured into the traction Battery into spinning the engine.

 

I'm wondering ... I also have a mk4 Yaris and the charge bar does indeed not go that much up during B mode. But as the engine is spinning, maybe mg1 is spinning too which generates electricity but is not taken into account on the regenerative braking bars. I dislike using B as it does not appear to charge but on the other side i've been amazed on how much it can charge during B coasting

B mode is for reducing brake fade not brake wear.

 

Go down a steep mountain pass for a few miles whilst constantly riding the brake with no engine braking assisting then the pads and discs (rotors) will heat up so much the brakes can become completely ineffective.

This is why sports cars will use disc that are drilled and vented to cool them as much as possible.
