It's interesting what would be the equivalent result for Chevrolet Bolt, as it's pretty much an equivalent car, but without the advantage of Tesla's supercharger network.
I don’t think it would be possible in anything like a reasonable amount of time. Non-Tesla fast chargers have huge gaps for a cross-country run. You’d have to spend days waiting for 6kW commercial chargers or 240V RV plugs charging you at 25-35MPH.
That doesn’t really address what I’m saying. The ability to use a DC fast charger doesn’t help if there aren’t any to use. Last I looked, there were no cross-country routes available using non-Tesla fast chargers. You’d need to cross large gaps on 240V charging alone.
Edit: just to show what I'm talking about, here's what plugshare.com shows for CCS chargers in the middle of the US:
That gap in the Nebraska is 336 miles long. Utah to Colorado is likely to be quite challenging with the mountains. East of St. Louis is another tough area.
I think you could do the trip entirely on DC chargers if you took some of the legs really slow to extend range.
The Bolt is EPA rated at 238 miles but on a long highway trip with not-terrible-weather it's trivial to drive and get 300 miles of range without resorting to hypermilling. A Level 2 charger would cover the 36 mile gap.
You'd expect to use a mix of DC chargers and Level 2 chargers. I think it's doable in both cars but I'd personally never take that trip in either of them. I don't know how often people are doing LA to NY trips that they'd ever decide between cars over their ability to do that vs just renting a car (or flying).
I'm surprised you can get so much additional range. My Tesla typically gets the EPA rated range in good weather at 65-70MPH. A 25% increase in range would require driving significantly slower than the speed of traffic. Is the Bolt's range really so understated?
LA to NYC is a pretty unusual trip. The Bolt is still a difficult sell for more typical long car trips, though. I've done a dozen thousand-mile legs in my Model S without a problem, but they'd be really tough in a Bolt. The chargers do exist for the routes I've taken, but they're not very conveniently located and often are single units, leaving you vulnerable to being blocked, broken, or in use.
I think the Supercharger network is adequate for road trips, but it's the bare minimum to make it reasonable.
