Yeah, don't spend that 400kW all in one place. At best, and it won't be, that's one way from Los Angeles to Portland, if you pretend that Mount Shasta isn't there. Plus it appears that unlike what was put forth to us as fact a year ago now only applies to 2nd owners of cars ordered after 1/15/2017 (a per kW charge). The 400kW bone does not apply to the Model 3 afaik.
What Model 3 owners are going to find out to their chagrin is that while it's absolutely possible to get all the range as advertised when traveling from one SC to another along a nice flat highway with mild weather at moderate speed, there's as much as a 50% hit during a week's worth of short urban trips. Meaning that their $12 (60kW * $0.20/kW in CA else e.g., $0.16/peak minute in, e.g., AZ)) doesn't get them full range. It gets them half range unless they're road tripping. Not a huge deal but it does negate their fuel savings relative to an efficient alternative vehicle.
So they'll just have to settle for a great driving experience and a safe car that looks, dare I say, really good from most angles.
What will be interesting to see in practice is the cost structure associated with the 12,500 L2 & L3 chargers from the utilities in CA combined with the tens of thousands of L2 & L3 chargers coming to CA alone from the Dieselgate money. Make them competitive with SC pricing and get municipalities off the schneid so that chargers more effectively penetrate residential MDU/MFD neighborhoods, and Good Things will happen.
As I've typed periodically - Solve California and you solve the continent.
