Understanding EV charging anxiety by mapping failure modes

I’m trying to understand why some EV road trips feel stress-free while others feel fragile — even when range and charger coverage look similar.

I started experimenting with simple “corridor views” that focus on failure modes instead of routing:
congestion, single-point-of-failure stops, lack of redundancy, timing effects.

Here’s one example (LA → Vegas):

Not selling anything — genuinely looking for critique from people who’ve done similar drives.
What feels accurate here, and what feels off?
