DCFC uptime is the single metric that determines whether EV charging anxiety is real or manufactured

The EV charging reliability debate drives me slightly crazy because it's often an argument between two groups talking past each other: Tesla owners for whom charging genuinely works well, and everyone else for whom it's more variable.

The data isn't complicated. Tesla Supercharger uptime is around 99%. Electrify America is in the 70% range. That gap produces very different purchase decisions if you're buying a non-Tesla.

Arriving at a planned charging stop to find 2 of 4 chargers broken isn't range anxiety — it's a legitimate reliability problem. The ICCT and other organizations have documented this with real data, not anecdote.

The NACS transition is positive news for non-Tesla EV owners. Access to Supercharger infrastructure meaningfully changes the reliability calculus. But adapters don't fix Electrify America's broken chargers — they just give you a backup option.

What would change my view: consistent DCFC uptime data from all major networks above 90%, published monthly and auditable. Until that exists, the charging reliability problem isn't solved — it's improved for vehicles with Supercharger access and unresolved for everyone else.

The numbers don't lie: uptime parity is the threshold. We're not there yet.
