I live in the US, and mostly use our 2018 LR Model 3 for road trips. Most are around 200 miles, some are quite a bit longer. I just don't buy that 400 miles is a realistic need for most people (even those like me who take a lot of road trips), even though many of them seem to think it is. I think it is a combination of the general public: underestimating how many chargers are available, overestimating how long it takes to charge, and drastically overestimating how big their bladders are.
True, the perception of the need is there, but it can be countered over time. Not to say there is not a 5% out there who really do need 400 miles range legitimately, but it is no where the majority.
What people really will go for are cars they they both want to own (suit their needs and their style) and that they can afford. For the vast majority of people out there owning an EV is just a theoretical exercise at this point because one or both of those things are not yet satisfied. Oh yeah, also convenient home charging availability.
