Angela Chao accident

[stopcrazypp]

It seems funny to use the term "gearshift" for anything on electric cars.

One of my Teslas has a stalk and one doesn't. It's hard to imagine making a mistake with the stalk. Move your hand up for reverse and down for drive, just like every car in the world. The on-screen "gearshift" is the opposite. Under stress, muscle-memory kicks in.

The mistake that is made is with the stalk you tend to not confirm on the screen what gear you are in so when you are doing back and forth gear switches (like for this three point turn), you may have flicked it in such a way it didn't register the change yet.

It looks very obvious that after celebrating the New Year, she was certainly drunk, but nobody want to mention it.

I agree, hard to promote negative possibilities when there is a death that seemed innocent
but should be considered negligent, feel real bad for the parentless child that now exists

For me, it is more intuitive to move my hand up to go forward and down for reverse.
I have made an error with the stalks on occasion because of this odd (IMO) setup.

Most of my past cars had shifters on the transmission tunnel.
I also am a gamer where ‘up’ almost always means ‘forward’ unless you are talking about flight simulators.

I always find amusing that when using the scroll wheel on top a mouse

- on an Apple computer is moving the screen down, while​

- on a Microsoft computer is moving the screen up.​

On motorcycles you rotate the handgrip backwards to go forward.

That design is ok for the rear doors because most modern cars also have rear child locks which can completely prevent the rear doors from being able to open. The design is that way likely for the same reason (so children can't easily find and reach them to pull on them).

I take it the government thinks the risk of a child opening the door is greater than it playing a role in a vehicle submersion accident.

The Model 3 until the new Highland refresh doesn't even have a manual release at all in the rear.

Great point, rear doors become traps for anyone if a rear child lock is engaged and you don't know how to bypass. Never really thought about it before electric locks. Now I wonder how my 2012 Tundra rear locks worked.

I wonder Tesla can add a 12(18?) volt lithium battery for redundancy to open the windows and to serve critical operations (display, cabin lights,...)

They do have that.

 

[rlsd]

They do have that.

Do you mean they have 2 in the car and if one fails the other one will take over?

No. There’s only one. What are the chances that the 12v would fail at the same time you drive into a pond? Extraordinarily unlikely. She probably couldn’t open the door because there were thousands of pounds of water pushing against it.

 

[ggr]

If it was 2020 with stalk, you push down for forward, and up for reverse.
If it was 2021 with on-screen shift, you swipe up for forward and down for reverse. BUT... it should have already selected forward unless there was something blocking the front of the car.

It's not just for opening the door in the pond. There are several other situations that need it.

You can also run the door locks off of the DC-DC converter from the high voltage system. I’m not sure of that covers a 12V battery short circuit failure though.
How often do those situations happen and how likely is it for the 12V battery to fail at the same time?

If the touchscreen goes blank, or other control buttons fail because of 12 volt battery failure on freeway the the second battery may help.

Why not just use the DC-DC from the high voltage battery in that case?

I don't know. If they can then it's great. I thought the high voltage battery is used for the power train only.

 

[Daniel in SD]

I don't know. If they can then it's great.

Yeah I’m pretty sure if the 12v gets disconnected it will run off the DC-DC. What I’m not sure about is what happens if the 12V battery short circuits.

I don't think so. That's the point of the fireman's loop. Once the 12v is disconnected, the HV contacts open and the DC-DC would go dark.

 

[Daniel in SD]

I don't think so. That's the point of the fireman's loop. Once the 12v is disconnected, the HV contacts open and the DC-DC would go dark.

Not sure what you're saying. If disconnect the fireman's loop the 12V systems are still powered off of the 12V battery. If you disconnect the 12V battery while the car is on the 12V systems are still powered by the DC-DC.
