Perfect if kidnapped or carjacked. Just open the bloody door and flee for help.

Now let's take it further, what exactly is wrong with the door sensor ? Mechanical or electrical fault ?

During the drive, the sensor suddenly stopped sending signals to the ECU or BCM and the car's computers assumed an accident and went into protection mode.

It is the same as Boeing 737 Max 8 and the AOA sensors. When the sensor fails, the MCAS system took over from the pilots and crash the plane.

Aiyoyo pilots must always be able to override any system just like driver must be able to take control of the vehicle in case of an emergency. If a vehicle is designed to make its own decisions without any input from the driver, then such vehicle should not be on the road.

It's plain stupid for such a sensor that was working before to fail suddenly and bring the vehicle to an immediate stop. The sale of such vehicle should be stop immediately and a thorough investigation conducted.

Got but they have 10 seconds to do it previously. When the plane already nose diving, 10 seconds simply ain't enough to disable the system.

Sensors have been in cars since 10 years ago. Any ICE with an ECU is sure to have sensors. Just that nowadays cars have more sensors for everything.

Once i had a Proton just lose engine power on the road. Engine management just appear on dashboard and even lost power steering. Lucky was not driving fast and not many cars on the road....

Previous sensors mostly for monitoring but passive.

Now more and more active sensors monitoring the car without the driver's decision making. It's like Skynet taking over your car and stopping as it pleases. Human drivers not allowed to do anything. One day, these cars may reverse the aircon motor polarity and suck all the air out from the cabin.

The main issue is the car programming how the car react and action when it receives the signal from the sensor. Faulty or not.

In this case, the programming is bad and not mature. The car wasn't fully tested in all situations.

All this Atto car need to be recalled to change the firmware. Otherwise, all this Atto is like time bomb on the road.

The buy back is because the owner has no confidence in the car. And this experience is a phobia for him. I guess he will sell if not buy back.

Humans are not perfect.

So, even the machines they created are not perfect.

Can't imagine if AI begining self aware next time. Due to an imperfect programming, all decision made won't be perfect either.

Voltage too low causing sensor to malfunction? Owh shit

This is true for cars with BCM (body control module) and a weak battery will make the unit go haywire.

For my Exora, a weak battery will cause all the lights on the dash to light up and gearbox durian symbol will appear.

For my forfour, the entire dashboard will light up and traction control plus electric power steering will stop working.

Old cars not affected. At most, the interior light will become dimmer and engine difficult to start.

i suspect rush to market as usual plus software stuff that can OTA they are more confident or likely to rush since can update later. But what if something happens before the OTA update happens? that's the problem with these manufacturers...

Follow Microsoft tactics. Ship first, fix later.

Do a door sensor need to be that sophisticated? What the door sensor use for?

1) door sensor can be just a contact switch. An On/Off signal to the ECU. No electronic require inside. Keep it simple, cheap and failsafe.

2) If there require some crazy electronic stuff inside the switch, the circuit can be design to take wide range of voltage. 10-14.4v is enough to operate and tackle the low/high voltage of the battery. Battery don't drop dead till 0v.

Some like Cybertruck has ECUs inside the doors.
