Probably not anytime soon. You can charge 240 miles of honest, comfortable, real-world, freeway-speed range while you sleep at night, and the same while you're at the office. Cross-country road trips are just about the only time the vast majority of people will ever need to charge at a location other than the origin or destination. Waiting for a supercharge doesn't add much time to the trip unless you normally tend to drive 10 hours straight without answering the call of nature. The superchargers are intended to be at locations and intervals where you would ordinarily stop anyway (to eat, use the facilities, stretch your legs, etc.). There are, of course, cases where a battery swap would be handy, but that's on the wrong side of the 80/20 problem.
