One aspect is that Tesla is all cameras, whereas Rivian sees it as important to have multi-sensor suites (cameras, ultrasonic, radar, and in Gen 3: lidar). TBH as a customer I prefer to know that the latter is protecting me instead of just cameras.

It also suggests to me a more-professionalized R&D culture.

Tesla claiming it planned to implement self-driving with just cameras has always meant I don't trust anything they touch.
