I think you would be surprised by the volume of traffic on US 395. Why do you think Tesla installed four superchargers on the route?
I was referring to feeble EV traffic on the 395. EVs like your Bolt (and in fact every CHadeMo/CCS sold to date in the USA is not a long trip car to anybody but a handful of enthusiasts like yourself. The remainder treat them as local/wide-local cars and that is where an infrastructure that extends their range in a way that people will use is reasonable.
Tesla are not feeble EVs due to their range AND charge rate.
I'm in partial agreement, but I think the Bolt and the other soon to arrive 200+ mile BEVs with CCS/CHAdeMO work okay as one QC each way trip i.e. weekend getaway cars. So, for Bay Area residents, putting a QC in Groveland or some point east of it makes it possible to visit Yosemite and return with just one QC stop along the way (each way), and even over to 395 and maybe as far south as Mammoth and return. Putting a QC in Inyokern, Olancha or Lone Pine allows Greater L.A. residents to reach Mammoth and return, although you'd also want/need destination charging there. Naturally, the closer spacing the better, which is why Tesla has SCs in Mojave, Inyokern, Lone Pine and Mammoth, is adding one in Bishop at some point, and still needs one in Lee Vining. Lee Vining, Bishop and Lone Pine are all about 1 hour apart, which allows un-recharged round trips to any point between them (plus some local driving), while only needing to charge to 80% or so ( I assume minimum of 15% reserve). Adding QCs in Inyokern and/or Mojave (plus Kramer Junction) allows for no worries in worst case conditions.
As the 150kW and then 350 kW CCS BEVs (and maybe 400kW CHAdeMO) vehicles begin to arrive, Tesla's QC speed advantage will no longer exist (they seem to be talking about going to 250kW or so), leaving them with their range advantage (and a more extensive network) as advantages for now.
