Unfortunately, the unique requirements of the Roadster make existing transmissions unsuitable, even though the transmission it needs is not rocket science.
But isn’t EM the “master of rocket science”? It is somewhat shocking that such a down to earth little problem is still beyond their grasp so far.

As noted in Elon’s Inc magazine issue, I argued for a simple, one-speed transmission for the first year or two of Roadster production to reduce risk.
Yeah, you might have noticed in the TM blogs that I had suggested repeatedly that a one-speed made more sense. I had no idea how much trouble you were having with the transmission, nor that it wasn’t your decision, but it just made sense to me for a number of other reasons:
1. One less engineering challenge for the small team.
2. Avoids a situation of prolonged heat stress on the air-cooled eMotor (during excessive top speed runs).
3. Doesn’t make much sense with the limited energy storage of batteries (range at 130mph is likely not very far)
4. You were trying to use much pre-proven technology and one-speed is the norm for production EVs.
5. Street cars meant for USA only have no business going more than 90MPH anyways.

a fiberglass body
Oh, I didn’t realize (until now) that carbon fiber body was another decision made for you. I have concerns over that decision as well, but (so far) there aren’t reports of problems there.
Like with the idea of the one speed transmission, I would have voted for fiberglass as well just as a cost reduction effort. We saw the Roadster price go up during the development stage… I had been hoping it would have gone down instead.
It sounds like parts of the Roadster were designed by “Fiat” (intentional double entendre)

conventional door latches
Sigh… I noticed at Pebble Beach that the rubber button door latches were malfunctioning. I didn’t blog about it because I figured it was something you had under control. Sorry to hear it was another thing you tried to avoid.
Perhaps your next product company will have more strict rules about who gets to redesign the product and when the design decisions are locked down. I know how it goes when someone comes in at the 11th hour and just asks you to absorb yet another minor little “improvement”.

less-than-perfect glossy finish on the airbag hatch on the dashboard
You should see how much difference in texture there is on the passenger airbag cover from the rest of the dash on my Lexus…

Elon felt that the very first model of the Roadster had to be the best car possible, and felt that the risk was worth it. You decide.
Yes, I did decide.
My cliche catalog runneth over:
“Death of a thousand cuts.”
“The devil is in the details.”
“…one percent inspiration and ninety-nine percent perspiration.”
The Roadster only really needs “bragging rights” in a few metrics:
#1: Best 0-60 for a production EV
#2: Longest range of a production EV
#3: Best handling production EV
#4: Best looking production EV
All the rest of those bells and whistles were unnecessary fluff.
