Or the foresight to have a small backup battery unit used exclusively for emergencies like say when the battery goes out or when someone reverses their car into a lake. The fact these are such death traps shows just how bad the US is when it comes to giving a flying fuck about people over money.
And all the while Elon is touted as some kind of super Lex Lutherian genius.
Honestly if I wrote a fictional book with some of the shit he's done and how the world looks at him publishers would throw it back in my face as being the most unbelievable POS they've read in the past 20 years.
As far as I understand, that 12V battery was that backup...
Nope it's a separate battery used like in a normal car to power the low voltage stuff so you don't have to use high grade power lines to run the windows and doors
During the pandemic my car sat in the garage until the battery died. After 7 hours of charging it, turned on the car and found the hybrid battery was almost full.
I get why the high and low voltage systems are separate, but damn that was one of those "Really!?" moments...
It's much much much cheaper to use the same 12V systems that other cars use.
Kia/hyundai solved this by having a disconnect on their (li-ion) 12V battery. When the voltage gets low it completely isolates the battery. There is a button inside the car that reconnects it right before starting the car.
The 12V is not a backup, it's the sole battery used to power electronics.
Not anymore, they've updated the platform to be 48v (which they shared the docs with the rest of the industry) and are using lithium batteries in both systems instead of lead acid. They're supposedly supposed to last the lifetime of the vehicle instead of having to be replaced every 4-5 years.

That's only the Cybertruck
The 48V battery will become "the sole battery" for the electronics so nothing will change in that regard. They're not connecting 400-1000v batteries to the electronics.
The point I was trying to make is that the model y switched to 12v lithium batteries in late 2021 that are supposed to last the lifetime of the vehicle (from the 2nd article). The 12v lead acid batteries you are used to seeing in every other car made since the 1960s usually only last 4-5 years.
I would bet that the model y from this story is either a 2019 or 2020 model
And what part of that were you referring to, specifically, when you said "not anymore"?
Only the cyber truck. Model S and 3 refreshes are still on the legacy platform, with a lithium ion 12V.
In this story, it's the model y.
I should have said a small battery backup done properly knowing full well the abysmal QA of that company.
Oh, well, then, ...
I still dont like something that is electric powered making it so you cant get through a door. If there is a short, the battery dies (which it will someday) or generally bad parts could potentially lead to a preventable death. Cars were made so keys (or key like) can open the door no matter what. And especially in the heat everyone is going through in the US.
There is still a mechanical latch but it is on the inside and is well-hidden.
It doesn't look hidden to me, I expect I'd probably use that by accident myself.
Front seat? Sure. Back seat? Nah. You have to remove paneling, pull a tab up, then pull a cord forward. That is a three step, non-obvious and non-intuitive way to open a door.
Or, climb into the front seat and open the front door.
Or, all doors should have an obvious mechanical backup that doesn't require that.
Agree to disagree, I suppose. It just looks like a piece of trim to me.
Lol its not hidden at all.
LOL ok
If you owned one you'd know i guess. The M3 has un hidden regular door pulls on the inside both front and rear doors. Idk about the Y.
I know it's cool to hate Tesla, but wrong is wrong, despite the downvotes.
I do own one, ya doofus.
Then how the fuck do you think they're hidden doofus. Every second passenger tries to pull them.
Ya I hear you. I don’t even like driving modern cars because they are all electrical and the pedals feel like video game controls. But nothing in the Tesla is built well. I fully believe it possible to build a full proof battery backup and not just hook up a random 12v that probably suffers from the same abysmal QA as the rest of the car.
