"The federal EV tax credit of $7,500 gets the price down to less than $30,000" [1]
"the estimated average transaction price (ATP) for light vehicles in the United States was $33,666 in March 2016." [2]
A car that costs less than the median purchase price for new vehicles in the US seems pretty close to "for the masses" to me. It's at least in the running for more than half of all new car buyers in terms of price (not in size or amenities, obviously).
