Hmmm. I've charged publicly ~100 times on the Tesla network (mostly cross-country, but some long city stays) and I've had to wait briefly twice.

I've had an EV since 2019 and did a few longer trips, including outside teh normal charging networks and I only had to wait fun line twice. It IS annoying when it happens, especially when I was in the middle of nowhere and the charger was being used by a pluggable hybrid

I've never waited. 95% of my charging is at home. The other 5% is Tesla superchargers and have never waited. At most 90% of slots taken, so close, but never had to wait so far.
