You really need to be in the middle of nowhere for a 200 mile range to be a problem. I've made quite a few trips in my Bolt where I worried there wouldn't be coverage (rural Indiana was my biggest concern), but it consistently turned out to be unfounded. In rural areas chargers certainly thin out, but you can safely drive the interstates and the vast majority of state highway with less than 100 miles between chargers.

The fact is you felt insecure because there was a risk. And with growing degradation means more of a buffer is needed. A 300 mi range vehicle is 192mi due to the buffer, and even that dwindles.

Only half of the non-Tesla EV chargers work, so your 200 mile charger now takes 6 hours to do the next 200 miles.

Even super chargers only function well over the bottom 50% of the battery . So the usable window is shrinking and shrinking.

All of these practical insecurities will need to be fixed before EVs expand beyond just a niche product.

You can dismiss them as silly or user error, but you won't sell any more vehicles that way.
