It didn't fail imo - it was intended a low-volume product for next-gen Tesla tech - Ethernet based fieldbus, 48V systems, area controllers etc. The philosophy is the same like other high-end cars - you field test your latest experimental tech first in a car with lower sales but high margins - if your fancy stuff has a 1% failure rate, in a 100k production run, that's 1000 vehicles - high but manageable.
If you sell millions and its your main product, your company is over. This is the same playbook German manufacturers followed since forever. I bet the next gen Model 3 and robotaxi will get the cybertruck tech.
It failed based on the sales projections that Tesla set. Also, several reviews have not exactly been kind, along with lots of comments from owners about annoying issues and malfunctions.
If Tesla needed beta testers for things they hadn't figured out yet there would have been better ways to go about that.
