When PIWIS3 connects, you should be seeing a warning on the IC that the HV battery is energized. You might be talking about disabling the HV battery via a physical switch under the good (it even has a padlock lockout feature) which is done for safety when servicing HV components.
While PIWIS is connected, HV battery is active, as is the DC2DC converter, why would the 12V battery run down given it's essentially always being charged (barring perhaps recoding around the DC2DC converter)? DC2DC converter is like an alternator in ICE cars.
This problem gets worse as ADAS gets better. That is why Google/Waymo skipped Level 3. If you only have to take over once a year, you will never be ready - that's just human nature. I can tell you from personal experience, at first you might be very vigilant, but surprisingly quickly your brain...
Sadly, I suspect a Model S Plaid same age as Taycan would both require much less service visits, and any visits which do happen anyways would be cheaper.
In the US prewire is an option you have to check when ordering ($140 IIRC). Check your car's build sheet to see if it has one. Some places, like UK, the pre-wire is standard.
As for how to run wires from the trunk (if you don't have, or cannot use the pre-wired power and/or video coax cable), I...
Of course FSD can and has avoided accidents. Great! It doesn't mean it can drive all on its own 100% of the time (or else Tesla would have had it certified as Level 5).
I haven't driven on FSD in a couple of years. I did take RoboTaxi recently, it did ok (operator did not have a take over, but...
There is a lot more nuance to this. FSD is better that the average human driver in specific conditions. It simply won't engage in other conditions. Notice that no autonomous taxis deploy in any area that hasn't been carefully mapped out by the cars themselves, and they will not operate in...
I have been reading lately about companies making and selling simpler, easily repairable, un-connected products, and how they attract customer demand, for example this Canadian company:

My mind started to...
To be honest, I think it's just an excuse. The same type of people who claimed in the past they are just fine driving after a few drinks, simply use FSD as a justification, but had there not been FSD, they'd still drive intoxicated (and plenty do). Way back around 2017 I met a drunk guy at a...
Google/Waymo research found that it’s not true. Paradoxically, the better the FSD gets, the more dangerous it becomes to the supervising human.

Think about it, how ready to take over would you be if your...
60A breaker allows for 48A max sustained load, which according to Google is the most a BMW iX3 will draw in North America.
80A breaker allows for 64A max sustained load. I've never come across a car which maxes out at 64A (typical Level 2 OBCs are 32A, 48A, 72A, 80A)
100A breaker allows for 80A...
80A * 240V = 19.2kW
where did the 15.4kW number come from (even if it's the energy making it to the battery, is BMW charging really only 80% efficient - most everyone else is ~90%)?
Unfortunately Porsche can claim the 48A draw was a bug, which they eventually fixed for all cars from before May or 2023 and after whatever date they went back to 9.6kW spec. That would leave a small delivery time window of Taycans which could sue in a class action. I think in Canada that window...
While I don't know the OP's usecase, I can share a real usecase my wife has encountered where 11kW charging allowed for some buffer charge in a Tesla Model S60D during winter driving. My wife used to drive about 150 miles in the morning to help out a family member, then got home, charged for a...
To be more precise, it's a 40 amps limit, even at lower voltage (so for example at 208V which is a valid Level 2 voltage often present at industrial/business sites, you will only get 8.32kW from the EVSE, so 7.5kW effective charge rate.
Tesla has a history of deception by relying on people not parsing their statements literally. For example (actual example from Tesla's past), Tesla publishes "Motor power", then people realize they are missing a 50% power boost to reach that. Tesla placates people saying more power is coming via...
I don't think they fixed the 11kW charger, it will still fail. It just helps Porsche simplify the global supply chain to only stock one SKU instead of two. That said, given comments here, they apparently can't even keep enough of just the one SKU in stock for some countries.
