Rivian has good software in general but my R1S still has plenty of bugs. My car was even bricked by an OTA before so there are real growing pains. They are also missing tons of features in comparison to Tesla (no surprise) and even legacy auto (texting). Since Rivian refuses to support CarPlay it's frustrating while they play catchup which will take years. Still generally a safer bet than legacy auto without OTA capability.I almost bought one for the engineering, I.e. the fabulous range. I bought a Taycan (apple calls it a Tarzan) GTS instead and I love it, EXCEPT for the range. The Taycan does have a few minor glitches with respect to CarPlay and keyless entry, but it drives like a dream.
I feel for Lucid, it has so much promise, but testimonials like this are going to kill it. They should merge with Rivian, reputed to have wonderful software.
