That is often the argument that i see but people forget a lot:
Fast charging if often 20 > 80% for 20min. If you want 80 to 100, its a lot less fast (think how your phone slows down).
While you can drive down to 5% of less, it can become a issue if you do not find a charger. When the summer vacation happened, a lot of north traffic goes south, over France ( and reverse).
What happened? People ended up waiting 15 a 25min at the chargers traffic jam in their cars. Then they charged up to 80% (because the stations had people to manage the flow), and needed to drive out (or pay more/fine).
This resulted that your range was already reduced by 20%. You ended up wasting 15 a 25 minutes stuck in your car. And with airco's on because its summer, so more battery drain. Aka, you did not really tank X km range, but X - waiting usage - 20% less limit.
Its always fun to compare a gasoline engine 5 min tank job, vs "not a issue, we need to stretch our legs", but when the reality of long trips that often coincide with vacation periodes... Yea, then the disadvantages of that statement come into play.
So the irony is that, a EV with a realistic 500km range, got hit with a 20% at chargers, then another hit from the waiting, o and you had no choice, it was fast charge or no charge.
I remember warning people to not see EVs based only on short trips or long "out of season" trips but also on those typical school vacation trips that many take. Ironic part, if you drove a hybrid, 5 min tank job for 100% fuel at the regular price.
