Reminder: radar used to be the "future of Tesla's self-driving Autopilot." If you read the afterword to the paperback edition of Ludicrous: The Unvarnished Story of Tesla Motors you know that Tesla even spent years developing radar in-house https://www.inverse.com/article/20833-elon-musk-radar-autopilot
If radar is so useless, why do the early Model Xs have brackets for corner radar? https://www.ebay.com/p/700484339 

The TMC guys even stumbled onto the fact that Model X was supposed to have corner radar: https://teslamotorsclub.com/tmc/posts/3223253/

Even Elon knows sensor diversity/redundancy matters.
The radar story matters because it reveals that Musk has been fumbling for a strategy even after he started taking customer cash for FSD, he was naive enough to think Tesla could beat Bosch/Conti, and that the north star for this safety-critical tech is cost and not safety.
Add up all of these facts, and there's no way not to conclude that "Full Self-Driving" is a scam. The most you can say is that Musk took consumers cash for a product he wasn't close to understanding, which doesn't make it any less of a scam. https://twitter.com/Tweetermeyer/status/1357147055127285761
I should add here: there is still a ton left to report on Tesla's in-house radar program and my reporting days are over (at least for the moment). If you're a journalist who wants to report this story out properly, hit up my DMs and I will help however I can.
