That's a pretty weird statement to make. These are rural freeway exits. The time to get from the NB to the SB side (or vice versa) is literally the amount of time it takes for the grand voyage across the freeway overpass. Twice, if we're being pedantic. In the cases where there aren't even stop lights at the top of the exit ramps, one is required to use the time metric of seconds to quantify the total "extra time" spent getting to/from the chargers.
That's terribly misinformed. Shasta has 20 chargers. While they're only 150kw, one can almost always find an unpaired stall in the 16 across the street.
FWIW, I'd encourage supercharging noobs to allow the trip planner to figure it out for the first few trips. Once you get some actual experience and understanding on how it all works then you can start folding in planner over-rides to improve the experience, whether it be for time efficiency, amenities, etc.
For those looking for useful 411, the 6 permanent 150kW stalls at Corning end up being pretty must obsoleted by the 7 Williams 250kW stalls (which is a comfortable first stop for a good portion of the northbound traffic from the bay) and the 8 250kW stalls at Red Bluff which are only 20 miles north of Corning (and are a decent long-leg from the bay). FWIW, Red Bluff chargers are kinda in a crappy spot for amenities compared to the others.
The inevitably unpaired Shasta 16 also land really nicely at the end of a leg from Williams, AND also make a satisfying long-leg pair from Bend (especially southbound if you start with a full charge). Fred Meyer is great and all, but Klamath is a little inconvenient if weather/wind/kWh permit. Its the better part of 10 min added time vs blowing through on 97.
