Very disconcerting event: I accidently touched, (brushed) the Start/Stop Button while adjusting the air vent above the start/stop button. The car turned off the motor and put a emergency message on the small screen in front of me stating pull over immediately, shift to neutral, hold the foot brake on and re-start using the start/stop button to start the car again. Needless to say, this was very disconcerting at 60 MPH and a scary situation in heavy traffic. Luckily I was able to do this safely and we continued our journey.

My question is how is this possible while actively driving a car? With the vent directly above the Start/Stop switch and needing only a very light touch on the switch, I feel this is a very unsafe situation! Admittedly I've put on ~5500 miles on the car and this is the only time I've had this happen. I would think you would need to push and hold the switch for a few seconds, if the car is moving to ensure you want to shut the motor(s) off. The steering and brakes continued to operate normally.
Ok after another forum member posted you can not just brush the button and turn the car off I tried it for myself. While rolling in a big parking lot I tried pushing the button to see what would happen. You can not turn the car off with a mere brushing of the button. You must fully depress the button a whole second and a half before the vehicle indicates it is off. I received message the vehicle was off and to shift into neutral and press the brake and depress button to restart. I shifted into neutral, applied slight pressure to brake and restarted all while the vehicle was still moving. Bottom line is you CAN NOT turn the vehicle off with just a brushing of the button. I see no problem with the design whatsoever!

Good point I didn't think about that. How do we get in if the key fob battery dies? Maybe this is a good reason to set up PAAK. Is there another way?
Yes, the key pad on the driver side b pillar. Did you not know you have one? šŸ¤”

It is possible you don't know how a BEV operates. The HVB is not connected and "on" all the time. It is only needed when it is time to move the car or maintain the LVB. That is the reason for the button. It isn't because it has always been there.

What if I want to sit in the car with the HVB off? It wastes a lot of energy to keep it connected and "on" if I don't need to move the car. And as already mentioned, there are many times when I want the HVB to stay "on" even when I am not sitting in the driver seat. I don't need the car to try to figure out what I am doing in order to determine if the HVB should be connected or not. I will tell the car what I want to do by pressing the button.

An emergency stop by pressing the start button is not the only good reason to have a button.

I don't think I will buy a car that doesn't have one.
Agreed. I much much prefer having the start/stop button. Call me a control freak, but when I turn off my car I want it to stay off. I had 3 for 3yrs. Daily phantom drain of 3% or more with the car just sitting there, and no I did not have sentry enabled when in my garage. No such thing as phantom drain in the MME.

You gotta give it to Tesla, having people believe every cost cutting measure (such as getting rid of buttons) they implement as "innovation". Next thing they're getting rid of on the 3 and Y are the parking sensors all around the car.

If the key fob battery dies then you can use the keypad on the B-Pillar.

But... if the cars 12v battery dies then you have to remove the front bumper plug and jump start the 12v. It would be nice if owners could get into the car without the need for electricity. If the car is in a front end collision and I need to get into an un-repaired car 3 weeks later because parts finally came in... how is that done? I don't know. Rip off the front bumper and the hood, I guess?

Exactly. A start button makes no sense in an EV. The startups don't have this legacy part. For some reason the old legacy OEMs want to do things like it has always been done, instead of innovating.

It is, to my mind, the biggest difference between Tesla and Ford et al- Tesla built an electric car. Ford built a car that was electric.
OK, maaaaaybe it's just me, but when I was driving my friend's M3 Tesla last year and went into a store to buy something using Apple Pay, only to discover that I'd accidentally left my PaaK phone (out of sight, but) inside the car, it was very disconcerting to realize that anyone could have walked up, opened the door, and driven the car away. There is simply no easy way to know that the car is locked or unlocked, or that it is (effectively) armed and dangerous.

My bad for leaving my phone in the car? Absolutely! But an on/off button, combined with the ability to lock the lock the door from outside, sure makes it less likely for this scenario to play out (IMO).

But yeah, I'm old.

I have yet to see someone explain how easy entry/exit would work in any sane way without a Start/Stop button. Of course, Tesla doesn't have that ability.

Interesting point. I guess it could work when you open/close the driver door, but yeah, wouldn't be as slick as what we have on the MME.

hmm. that would work on entry, where when you closed the door the seat would move into "drive position", but when you stop, you'd have to open the door, then wait for it to finish moving before you get out... that's assuming it used the keycard or PaaK to indicate that the seat shouldn't move forward when you've gotten out and the door was closed... otherwise you'd have to wait for the seat to move back when you're getting in, after opening the door.

so I guess yes, it's possible. I wouldn't call it "sane" though, but at that point it's an opinion thing not a fact thing. šŸ˜…

Shift to neutral or park - seems like pulled over in park is the step?

Push the button to put it in park, wait for the seat to move to the exit position, get out of the car. When you get back into the car, press the brake to turn the car on, wait for the seat to move to the drive position, drive away. Very similar to having a start/stop button, where you turn the car off, the seat moves to exit position, you get out; get in, push start, wait for the seat to move to drive position, drive away.

/Entirely theoretical. I've never used/wanted to use/considered using easy exit.

Sure, although you're now changing the pressure on the brake as you wait, assuming you're able to comfortably use the brake at all with the seat in the back position.

Also, this assumes park = the driver is getting out of the car. However, in an EV, it's perfectly reasonable to have the car in "Ready" ("started"), but in Park, while waiting for a passenger to get in or get out of one of the other seats. (that's actually reasonable in an ICE vehicle as well, but that's sort of irrelevant here.)

These are vaguely edge case, but they are all solved with the current setup.

It is already set up with a unique permanent default code. You should have a card in your document booklet. Maybe check the glovebox.

You can also set your own code that might be easier for you to remember. The default remains though. I don't think there is any way to disable that one.
