Why does it matter if your ev gets a 250 vs 500 range? The only time this is relevant is for long road trips, and in that case you have superchargers. For most people the distinction is irrelevant.
The 200 mile range or so seems to be the sweet spot where you can plug the car in every night and never think about it; on any given day you are not going to drive 200 miles other than the rare days you have preplanned road trips. The key point to remember is the car is recharged every night.
On the contrary, I think the reality of tens of thousands of people owning teslas and never complaining about the range (in terms of practical effects) is evidence that the technology is there.
What additional evidence is needed for someone to be convinced that technology is "there yet" beyond the adoption of electric cars by consumers because they are simply better products, as is the case with the model S? Clearly the technology is there, it's just only available (like most new things) in luxury class cars. If the argument is that somehow Model S owners are willingly sacrificing features (since the technology isn't 'there yet') in the name of some higher good like helping the environment, that's ridiculous, my wife has one and it's superior to a gas car for a long list of reasons. (With the minor exception that if we decide to take a long road trip, we need to plan ahead for a few minutes to ensure we can hit a supercharger.)
