> it's kind of wild that a couple of those crashes would've been easily preventable with parking sensors that come equipped as standard on almost every other car

Teslas are really cheaply made, inadequate cars by modern standards. The interiors are terrible and are barebones even compared to mainstream cars like a Toyota Corolla. And they lack parking sensors depending on the version you bought. I believe current models don’t come with a surround view camera either, which is almost standard on all cars at this point, and very useful in practice. I guess I am not surprised the Robotaxis are also barebones.
