I believe the "advanced" LKAS on Rivian only works on highways and relies on an "up to date" geofencing database, so that's the first-order technical reason. And I'm sure they don't exactly prioritize fixing or altering that behavior for the other reason.
how would that even work? even if you could generate accurate maps of lane markings, non-differential gps in not accurate enough
This is a safety issue. I don’t think there is a “fix” for offline lane assistance that they are sitting on do avoid people from disabling telemetry
The gen 1 system uses cameras primarily. It’s not awesome lidar or AI. It needs up to date road information.
I’ve been driving down I-5, a major interstate and had it turn off on me, presumably because I hit a dead spot, as conditions were fine and I5 is one of the most popular routes there is.
I’m fine with all of this. I prefer that it hand back control to me rather than make me another statistic like Tesla’s system.
