It's only relevant insofar as fast charging stations have a huge impact on how long you have to wait. The fact that basically only the Tesla network offers this is a pretty big limiting factor.

Yes, but it's not really a limiting factor or fair complaint about EVs in general. It is perhaps a limiting factor for people who only consider non-Tesla EVs and don't want to wait for the Tesla Supercharger network to become available to other brands.

I think there are more buyers than you think that don't want a Tesla.

I shouldn't have to say it again but this is not the point.
