If one looks at the charging sites listed, many are either private or in pay parking lots.
The placement of Level 3 chargers at sufficient well-chosen, properly-spaced, easily-accessable points along I-5 (and other transportation corridors) will be hugely significant.
With a L3 charger every 50 miles on flat land, and 25 or so in hills and mountains ... what a day that will be.
Level 2 chargers do not really help all that much unless you happen to be spending significant time parked there. If we had plug-in L2 EVSEs, just 240v sockets would be sufficient ... but, I suppose they want to be able to charge for the e-fuel.
An L2 charger can fuel only one (or a small few) cars a day. An L3 charger may cost 5 or 10 times as much initially, but it could fuel 20 or 30 cars a day. I suspect, for a real e-fueling business, only the Level 3 Quick-fueling will make sense (with a few 120v, L1, and L2 connections for non-L3 vehicles.
It will be interesting to see how the different factions compete for our e-fuel business. Will there be different "brands" of e-fuel, black e-fuel, green e-fuel, red ... ? Already there are different "brands" of e-stations.
