Why would it do that?
Ps I don’t pretend to be superior, it come comes naturally. “Fries with that yeah?”

Mazda 3 petrol Auto 2016.
Put say a Yaris, Prius etc in neutral, have the lights, radio and whatnot on and see how long the aux battery lasts.
The engine won't kick in in neutral to charge it, the car literally tells one this.
Surely someone with your extensive technical ability knows that.

Surely it has a DCDC converter to drop the voltage from main HV bus to the 12V battery?
Oh yes it does. That’s why I was trying to help you out here but like a typical MOT tester you think you know better and regardless you are now on my black list so join the Nasher club. Have a great day. Cheeseburger no cheese please.

Auto hold is ace for this but other cars with creep intend to just pull the electric handbrake, most the cars I drive auto disengage the handbrake when you press the throttle so it makes it all pretty slick in terms of moving away.

I should mention that the Mazda 3 has the Auto Start Stop feature which will kick in the engine if I take my foot off the brakes.
Edit: It does have a manual handbrake which I will engage before, which will stop the engine from starting.

Which can also discharge, hence the user manual carrying the warning about leaving it in N for a long time
Nope, it most certainly will not.
Factory trained Toyota/Merc/Honda tech actually, I just choose to stay away from main dealers now and work for a friend doing MOT's.
Far less silly people to deal with.

Ah I've seen a few break down in the drive thru, that explains it. Terrible design there then?
I never put it in neutral in the old slush box autos but now with Ford Powershift (2010) I just knock it into neutral if it looks like a long stop then flick it back when light go amber. Wife would sit with it in drive even if in a long stationary queue -I personally think it wears box if sat for a long time in drive.
All I can tell you is that the owner's manual for all the automatics I own or have driven and bothered to check say:
-Do not regularly put the car in and out of Parked while driving i.e. don't use it at lights (I assume due to impact on component lifespan).
-Only use Neutral in emergency situations like recovering from an engine fault or stall while driving or if the vehicle needs to be pushed a short distance (up to ~100m).
EDIT: On some it does mention using Parked if sitting at a standstill for extended periods while driving but also cautions against regularly putting the vehicle in and out of Parked while driving.
One of the issues is unless you fully go into park the brake lights usually stay on which bothers some people - there isn't the equivalent of the functionality with a manual to get them to go out while stopped without going fully into parked. This is usually true for EVs as well.

depends if i've turned off auto stop-start or if i've left it on
auto stop-start on:
park + handbrake (saving the petrol innit
)
auto stop-start off:
neutral/drive + handbrake or just the foot brake...
...depending on how far i am from the stop lights and whether i expect to move off soon or not

I hold the left paddle until one-pedal-drive engages
No engaging of handbrake
No faffing around and delay in pulling off when the lights change
No blinding the driver behind by having the brake lights on constantly.
It's a win all round!

I stick the handbrake on and leave it in D but it will be very car dependant.
In my one there is a tiny slither of blue in the 'drive' section of the power display if I hold it on the footbrake. I guess its holding a bit of torque in the hybrid motor to act as an auto hold the moment I come off the brakes before it starts to creep. If I stick the handbrake on that disappears, also gives my foot a rest
The last auto I drove before getting my current one was a 2008 Audi A8. I did the same thing in that the first set of lights I came to and it just dragged itself slowly forward with the rear brakes creaking.

Ok just seen this.
We have a an automatic with stop/start and you leave it in drive. When you stop with brake pedal depressed and in drive the engine stops.
When you take foot off brake the engine starts. If you’re on a hill the brakes are automatically kept engaged for 10 seconds or until the engine pulls the car forward.
No need to select park.
Note that park physically inserts a block pin that blocks the transmission from rotating and so prevents out front wheels turning. The parking brake only applies the rear brakes.
So applying P + parking brake means all four wheels are locked from moving (good on the eurotunnel).
Only time I park+parking brake is if the traffic has got to the point people switch engines off etc.
I’ve had an old auto rental many years back that didn’t have any hill start etc and that you had to apply accelerator and release brake like a manual.
My manual, sport and flappy paddles only really “suggest” the gear change. On manual mode you don’t stall the car by sitting still selecting first with foot on the break. It’s clutch is more intelligent than that.
