We take long road trips, with three dogs, often. The anxiety of thirty minute charge stops just isn't super fun (we've tried it).

Range anxiety is probably the only reason one would choose a PHEV these days. They’re slightly cheaper also but that’s unlikely to be a factor.

might depend on the country.

US/california would probably be 50c/kwh (though gas there is close to $7)

all other US states are less (for now, datacenters, ugh)
