I don't know if this is the case with multiple motors on EVs (i.e. if they continue to work and the non-functioning motor would disengage), but, I believe, multi-engine aircraft are supposed to be able to keep the airplane in straight and level flight if one engine fails.

Before I outline my thoughts on this topic, the most important thing to point to is the fact that those negative consumer report rankings have been updated for the 3 and S. Only the X remains on the consumer reports naughty list.

As to 'Quality' scores, I think it's important to think about the electro/mechanical systems as separate from the 'fit and finish' elements of the vehicle. As a truck guy, its really just a matter of time before I damage my truck. What I care about is that it runs when I need it.

On that point I offer these thoughts:

1. The video interviews with Sandy Monroe are really interesting on this front because he basically said of the original model 3 vehicles that the build quality was sub-par, but that the electro/mechanical systems were some of the most impressive he'd ever seen.

2. There seems to be a general trajectory of significant improvement on the build quality issues across the line for all the Tesla vehicles.

3. There are just far fewer 'failure points' on teslas than on ICE vehicles. Less places to fail SHOULD result in less failure.

4. Outside of the Tundra, all full size pickup trucks have mediocre reliability scores. I think part of this is how we use trucks. When you beat the crap out of something, bad things eventually happen. Part of the reason Toyotas are so bullet proof is that the 2019 models are almost exactly the same mechanically as the 2012 models. They evolve VERY slowly to achieve that amazing reliability.

5. If you want to be an early adopter, you should be prepared to deal with early adopter issues. My bet is that there's going to be some issues with the Gen 1 model. I think Tesla has learned a lot from their other models and that they designed the Cybertruck to be a monster but you don't know what you don't know. I believe in Tesla. I own the stock and I've reserved two Cybertrucks, but I'm not expecting perfection, I'm expecting to feel what it's like to ride the future before everyone else and that comes with some risks.

6. Despite their issues, used Teslas tend to have some of the highest resale values in their class. I don't expect that to change anytime soon. To me, that says something about their long term utility.

The working aero engine takes you to the scene of the crash.

So at least one guy apparently caught on that the "pointless, fuzzy math" that I put in an earlier post was borrowed from the aviation anal;ogue. Clearly a motor failure in a BEV is not going to result in a change in altitude and, clearly, with a dual motor vehicle, you are going to continue in a straight line. But if you had a motor failure in one of the rear motors in a TriMotor there would be a torque to the side of the failed motor. In an airplane this is a big deal as most single englne failures occur at takeoff but are rare enough that pilots aren't trained enough in engine failure, don't remember "dead foot, dead engine" and feather the wrong prop. Assuming he gets the correct prop feathered obviously he must hold a lot of rudder (or set a lot of rudder trim) to the good engine side and this increases drag, which with, the loss of power from the failed engine, results in a lower service ceiling. I remember looking pretty seriously at a twin many years ago only to drop it like a hot potato when a guy I met at a party who worked for the FAA pointed out that this model would not hold altitude on 1 engine. I don't think any commercial aircraft would get certified could it not hold altitude in the case of engine failure(s).

With a TriMotor CT it's the computer that remembers "dead foot dead engine" and steers to keep you on the road but you wouldn't want to go rolling down the road with steering "trim" set, not if you value your tires and so there will be a screenfull of warning with chimes advising you to get off the road and call service.

I guess it's worth reiterating that given that you don't want to drive on remaining motors after a motor failure you are off the road given a single motor failure and therefore you are three times more likely to find yourself on the side of the road from motor failure in a TriMotor as in a RWD. But it will be easier to pull off the road safely.

As to general quality: I picked up a new X Thursday and every thing looks good so far. If I go really looking for imperfect panel alignment I can probably find it. Delivery was flawless and a month earlier than promised so it appears that they have stomped down some of the problems they were having with the 3 ramp up.

Congratulations AJ!! That’s awesome!
