Tesla making way more cars than they can sell

As I prepare today's issue of The Sizzle much earlier than usual because I have to take my shitbox 2021 Model 3 all the way to Richmond due to a fault with DC charging where the car randomly decides I can't use a Supercharger, making journeys more than 200km from home impossible. This is the 3rd time in 3 years I've had to take it in for something relatively major. The heat pump shit the bed while I was in Brisbane a few months ago requiring a total replacement and it was delivered from the factory with a totally misaligned suspension that was unsafe to drive (Tesla deemed within spec, my local mechanic is the one who fixed it), so it is of no surprise to me that Tesla's sales numbers are collapsing. In Q1 2024 they built 433,371 cars but only managed to "deliver" 386,810 of them. Over on Reddit someone realised that since 2022 Tesla has built 144,000 more cars than they've given to a customer - where are the cars? Has everyone who wants an expensive EV got one? Are people put off by Elon Musk's awful personality? Do Tesla simply make poor quality vehicles? Is it all of the above???
