Last I checked 230 + 230 = 460.
So if the shortest route is nearly 400 miles wouldn't the 230 mile battery pack work fine? I mean yeah you have to account for getting out of an into the city, but 60 extra miles seems like enough to me. So the owners of the 160 mile battery wouldn't be able to make it, which given the market for Tesla cars, I'm sure is a minority.
Additionally this is supposed to be the first of many, so they'll just have to wait a bit longer.
I may be wrong, but the submitter of the article seems to want to label this hope instilling progress as either not good enough or proof of electric cars not working, I'm not really sure.
