I only got behind the wheel of a Tesla at the end of September, but I seem to recall even just TACC doing this when on a navigation route (i.e. you don't need autosteer running). I thought this was normal?

Yep, noticed this a couple of months ago. But it's a pain in supercharger-lite regions such as Tassie!
It doesn't know that fast/ultra-rapid chargers exist, so it often tries to route me to the only supercharger in the state (which is behind me, relative to my destination) so I would ignore it, but also take advantage of the fact it was pre-conditioning the battery (for when I arrived at the ultra-rapid charger).
However, now whenever I pass a U-turn spot on the highway it automatically slows down... annoying when it's every few km.
I can, of course, tell it to not route to superchargers, but then I don't get the pre-conditioning benefit.
How much time does preconditioning save - especially in QLD when ambient temps are going to be higher - especially in summer

The best example I have of when it may have been useful is after disembarking the ferry in Devonport at 6.45am in the middle of winter, and driving 100 km to a 350 kW charger - this was my charge curve:

Some further information here: Supercharging A Tesla In Winter: Preconditioned Vs. Cold Battery Test
Valid in scandinavia but what about Queensland where its beautiful one day and perfect the next... (as per the question posted in #6226 whose location is Brissy)
It's a good question, and I guess it depends on the state of charge and how much you're trying to add before moving on... all I know is I have plugged into a >100kW charger in QLD without preconditioning, and the charge rate was limited whilst displaying the "you didn't pre-condition your battery" warning. Not sure how long it took to get it up to an acceptable temperature to fast charge, but it felt like a while. Contrary to popular belief, it isn't 30degC and sunny in QLD all year round... but I take your point, it would be much worse in colder regions.
If a battery is at 30⁰C how long does it take to raise the temp to the preconditioning temp of say 45⁰C?
I don't know the answer to this, but I am far enough north that our days have been over 30 degrees for a good while now. I charged at a 50kW charger (usually 44kW in reality) and the car notified me that it was warming the battery to allow faster charging. It's always done that for any DC charging. If it doesn't make much difference, I would rather save the power and associated cost.

Can someone straighten me out on why our friends MYRWD (6 weeks older than our MYLR) software is different. When she selects reverse both side mirrors appear on the screen under the reversing camera. It doesn't on ours and I can't find a reason why?
Swipe up on the screen and it'll show you
To be clear, swipe up when the camera(s) are showing.

However, in our friends MYRWD, they don't have to swipe up, the side mirror view is already there.

They (or someone, maybe the delivery centre employee showing them the car) had to swipe up at one point, but it stays there every time after that.
