Right now the "alternative charger" option while traveling seems to be "stop at SC A with 50%" or "stop at SC B 50 miles down the road with 20%". There's no option of "this one is busy so I'll just go to that other one a couple minutes away". Having alternates, even if they're at the same exit, would be nice.
Some other suggestions...
Reliability is paramount. Location, amenities, and features are useless if I can't charge; the reliability of the SC network is why I went to an EV at all. It drives me nuts when gas stations have multiple pumps OOS or the card reader is messed up; at a charger with no local alternative (and maybe no other chargers in range at all) that would be unbearable.
The amenities matter to the overall experience (and eventually, will drive usage once more alternatives are available). The SC right near my house is a great location (though I never use it) being near several restaurants and at a good local gas station chain with clean bathrooms and surprisingly decent food. Note: amenities that would require crossing major multi-lane busy roads on foot don't really count--for example the Macon and Dublin (Georgia) chargers would really benefit from being on the other side of the street as the food choices are better.
Not only should the parking not be tight or confusing (looking at you, Parker's in Metter) but there should be at least a couple of pull through/trailer friendly stalls. "Normal" stalls should leave room for bike racks or hitch carriers.
It's time to start building out charging along more state highways, not just interstates. Yeah, start with the interstates, but the smaller roads go more places and offer more interesting drives. And folks outside majore metro areas will be more likely to buy in if they see they're being supported.
We (and many other places) could use some L3 chargers, even lower end 50kW ish, in town for the cases of "I need a bit of margin to get back home". I have to plan carefully and leave plenty of margin heading into Savannah because the only superchargers in the area are basically right near my home, so they do me no good when I'm out. Could also use a bunch of these in smaller towns etc so visitors have somewhere they can charge.
Public L2 charging is rare and takes forever, and often not conveniently located. For example, where my in-laws and parents live all but one of the public L2s is at some random business (like an insurance company or a small factory) off on a side street somewhere well away from anything else. How does that benefit anyone but employees? Public L2 should be for places where people will be parking for hours/overnight, not for quick shopping trips.
I don't "shop around" for charger prices, mostly because there aren't really alternatives. Eight V3 superchargers vs. a single 62kW CCS that's broken half the time? No comparison.
It sure would be nice though if Tesla had "minimum battery level" settings for the navigation like ABRP...
