I pulled the 200 mile range out of the air. Just picked a number for grocery getters, and running around town.
The average American commutes 42 miles per day, so based upon a 5 day workweek, they will need 210 miles of range, plus a 20% reserve of 42 miles, so let's say 250 miles. Allows for charging on the days off.
Since the batteries make up the majority of cost for EV, and the luxury model glamor accessories, are a draw on power, if they cut the power hungry options down and downsized batteries, they should be able to get an everyday $35K car to market.
