If "usually" your destination is another supercharger or somewhere you plan to stay overnight, then yes.
That's what I meant, as that's how the vast majority of Tesla owners plan their trips. Supercharge mid trip, destination charge when [at least] a few hours are available. Those who have more adventurous situations are more advanced than a noob thread for supercharging etiquette...
...if you're on a trip that involves multiple superchargers the last leg is a good place to "top off with the good stuff" since every destination outside of supercharger country will be painful by comparison.
Sort of. From a wasting your time perspective (which is the point in contention), the math still ends up in favor of moving along over 'topping off'. Certainly it depends on your battery size and your downstream charger speed, but once your SOC gets into the mid-high 90's that slow charger down the road is going to charge faster than a superchager at the end of its taper. One time I got a supercharger down to 2kw. :scared:
In an effort to minimize further semantic dissection, I'll revise my previous statements in context of supercharging etiquette: If you supercharge past what you need, where 'need' encompasses your assessment of your down-trip charging situation, personal safety margins, etc., you should be at your vehicle and willing to give up your stall.
