You forgot that geography, winter, 80mph interstates, headwinds, battery degradation and return trips are things. I consider my SR+ to have a usable range of 300km (travel speed 115km/hr) in the summer and I'd guesstimate I lose 4km of range for every 1C below 15C (less if sunny).
As an example (when the border opens), I'd like to take another trip to Texas to see Starship fly, but as of right now there are 4 gaps:
Fort Macleod to Great falls (347km) - Must L2 >1hr
Great Falls to Billings (355km) - Detour to Big Timber (+45km, 20mins)
Trinidad to Amarillo (363km) - Must L2 >1hr
Amarillo to Sweetwater (401km) - Must L2 >2hr
