Haven't they? They've removed radar from their cars and now the AEB system uses image recognition. Does any other manufacturer do that?
"General Motors said Wednesday that automatic emergency braking will be standard on 98% of its new vehicles by Aug. 31, the end of this model year. The four remaining automakers were close to hitting 95% in December."

If Tesla decided to make their suspension entirely out of carbon fiber despite knowing carbon fiber handles stress cycles differently and tends to fail catastrophically at the limit then you'd have an apt comparison.
Or you can look at the Boeing 787's carbon fiber body design as an example of how to do something completely differently. They deviated from the norm but that involved years of engineering and testing to identify potential failure points, how operating conditions impact the service life, etc. They designed inspection schedules and procedures for out of spec events like excessive G-forces, hard landings, explosive decompression, over-pressurization due to pack failure, and so on. All of these things are well known with aluminum airplane bodies but not for carbon fiber.
So a 787 operator knows if they have an explosive decompression event exactly what needs to be checked and how many flights to shave off the expected service life.
From what we know right now Titan had a unique hull design yet did absolutely none of the engineering or testing legwork before putting paying passengers inside. That is what makes them reckless and Boeing or Tesla not so much.
The failure modes for a vehicle are also a lot simpler than a sub. If the interior starts to fill with smoke you can stop and get out. A submarine doesn't have that option.
