One change that people don't appreciate much is that Tesla has gotten much better at making their cars. While other automakers now have models which spec-wise are competitive with the 3 and and Y, only Tesla and maybe BYD can make EVs profitably at scale. This is why they've been able to cut prices and still be decently profitable - a Model 3 RWD costs $40,240, which is about $33,500 in 2018 dollars (when the Model 3 started selling). I expect legacy car makers will follow Tesla's lead on this process (and switching to 48V) much as they are now following and introducing large castings in their cars.
