Don't believe the clickbait. The solution is straightforward: more charging stations (to mitigate stalls or entire stations being down), a bit more user education (cold batteries charge slower, and if the vehicle has enough battery charge, will improve pack temp on the way to the fast dc charger so the battery is warm on arrival, to optimize for optimal charge curve), and probably a bit of software tweaking (don't route to down fast dc chargers, improved polling rate of stations for health to communicate to the fleet availability for nav). Perhaps some improvement for cold weather chargers is needed as well, to route cable coolant (which keeps conductors thinner for UX and cost) to other key components to keep them at operating temp. Tesla should be able to figure this out, considering how they use a heat pump and motor stalling to warm the vehicle battery pack when needed.

Tesla is on version 4 of their Supercharger, and many improvements have been made since v1. Iteration is progress, expect it to continue. We're only at the beginning of a historical mobility transformation.

(own several Teslas, in 6 years have never arrived at a down station in over ~200k aggregate miles traveled long distance in the US; one of my residences is in the greater Chicago area, so I am very familiar with the charger network there)

Frozen Supercharger connector is not a clickbait. It's a reality of -9F over 3-day weekend.

At some stations snow drift would be up to the charger so that cable may accidentally fall into the snow when putting it back.

I can see how such connector would be then put upright and the moisture would end up in the mating holes.

Also, waiting in the line at the charger (some waits were over 1hr) would likely cool the battery, unless driver would manually keep the battery conditioning on, which eats the charge too!

Then it goes to slow charge due to cold battery. Which increases the wait time to the others in the line...

Dismissing these issues on personal experience does little to improving the infrastructure and charger design.

Gas stations screw up too.

There was a case where they hadn’t properly desulpherized gas down south so the fuel contained an acid that damaged the fuel gauge so the gauge would always read “full” and you’d drive till you ran out of gas.

There was another case where gas got contaminated with water in NJ which led to the strange spectacle of people noticing a lot of broken down cars as they approached the gas station, then they drove a block and broke down
