I'm afraid it's exactly the opposite -- Tesla has awful software, and no self discipline about adding more bloat. There is a lot of rigorously designed software in cars where you can't see it. Jeep is no one's idea of quality in any respect though.
Legacy brands do significantly improve software as the model evolves, and provide firmware updates to earlier models. The best car is probably the last one before a new platform step change.
Tesla has also pioneered putting large amounts of software in mission critical compute like instrument displays and touch screens, disregarding decades of careful evolution in HMI and TCB design. There is so much wrong with their cars without even touching their autonomy system, a proven killer.
