Heh. I won't say they never work, but my job regularly has me doing 100-150 mile trips *daily*, some cases 200 miles. The cheaper EVs would not work, but a vehicle with a range like the Tesla 100d would suffice...If i charged it almost nightly. For the record, I am a roving network engineer that covers an area with the landmass roughly half the state of Rhode Island (around 550ish miles). I drive a 96 volvo station wagon that averages mid 20's mpg, going as high as 31 MPG on the highway and as low as 20ish in the city. It costs almost nothing to run besides tires, brakes, oil changes and suspension and I do my own maintenance. I love what Tesla is doing, but probably won't buy one until I can get it for less than $5000, I can do my own maintenance and it can haul me, plus all my gear comfortably. I'd imagine for a niche case like this, it may take awhile..
Plus, I wonder how long it will take to trickle to those who simply cannot afford new cars. To those outside of the new car market, there exists an entire underclass of used vehicles and the industries that spurs along. Think shadetree mechanics, places like autozone that sell parts and places that refurbish used parts and sell to the consumer or mechanic. I wonder how EV battery life will look after 10 years. The cottage industries that will no doubt arise selling refurbished batteries and/or doing in-car cell replacement for those who cannot afford to swap the whole unit. As a guy who swapped his own transmission over two weekends, I"m more excited about the prospects of how cheaply I can own and purchase a car, rather than the mass market $35k unit.
