Comment Lidar is nice, not required (Score 2) 178
I think the Rivian approach is the best. They're basically copying the Tesla model of having their fleet send the sensor recordings back and then using them as training data. While they're far behind right now, they'll catch up quickly, as they can copy a lot of the basic technology that's now established instead of having to invent everything from scratch and make wrong decisions along the way. The difference is Rivian is including lidar, so they just include the matched video and lidar recordings as a larger training data set. I'm convinced that if the price of lidar was more like it is today back when Tesla started selling FSD in 2016, then that's exactly what Tesla would have done, but Tesla is now stuck with their solution with ten million cars already on the road.
But in clear weather conditions, I don't think lidar really helps that much. Most human accidents would be avoided if drivers had better situational awareness and didn't have gaps in paying attention, and the cameras solve that.
