I'm an electrical engineer who has owned a hybrid since 2000, and done a lot of research on extending battery life. I've discovered that Lithium-ion batteries don't like to be charged below 20% or above 80% so that limits the useful battery range to 60% of the EPA rating:
60 kW car: 0.6 times EPA == 125 miles
85 kW car: 0.6 times EPA == 160 miles
I would recommend no long distance drivers buy the 60 kW car, and instead buy the maximum capacity battery Tesla sells: 85. Then install superchargers along all the crosscountry interstates (I8, I10, I40, I70, I80, I90, et cetera) at 160 miles minimum, so the batteries can be maintained between 20-80% charge & maximize their lifespan.
