I'm in the market, and the answer is kinda, for non Teslas. I do a road trip up the east coast a few times a year and the Tesla will reliably add about 4 30 minute stops on each half of the trip. A non Tesla also requires four stops, but they could be anywhere from 20 minutes best case to 1 hr plus, depending on the availability and status of the unreliable chargers.

A lucid with 400 miles of true range would probably cut it down to two stops, but I don't have $140k

So for me I make a trek to my parents house ~150 miles away a few times a year.

In good weather (and good battery condition), I could maybe skip hitting the chargers all together, or get a little bit of charging at my parents house from a wall outlet.

Unless my parents (or my grandfather that I also visit fairly regularly who lives the same distance in a different direction) installed a better charger at their place... In colder weather (e.g. Christmas), I'd almost definitely need to use a charger while going at least one direction.

The problem is, in both cases, there are like 5-10 charges total (not charging stations, chargers) where as there are like 5-10 gas stations all right next to the interstate each with at least 4 pumps, many with 8+ pumps.

I'm concerned that during peak travel in cold weather (e.g. Christmas time travel), I could easily find myself in a bad situation where I can't get a charger because they're all too far away, broken, or in use. There's just not enough redundancy.

No, there are very few places like that, and most of the populated places are not at all like that.

I took that to mean “I want to complete my common road trip without charging”

A few weeks ago I did my first road trip requiring charging away from home and it really was painless
