Almost all of the issues and frustrations that Marie ran into were new and/or unique to electric vehicle (at least initially), as she pointed out.
- EVs have shorter range: ICEs were similar in that fuel tank capacity hasn't changed much but engine design advancements improve fuel efficiency and in turn increase range.
- Charging stations are far and few between: same with gas stations in the early days - urbanization creates more of them.
- Different levels of charging station (1.8kwh home charging, 6.6kwh public charging and 24kw+ DC fast charging, colloquially Level 1, 2 and 3 charging). This is not the same as fuel grade. But it's obvious that just like a cellphone charger, higher output charger can fill the batteries faster.
- Range meter is a guess-o-meter. This is exactly the same as your ICE's range meter. Driving style affects fuel efficiency. Heavy footers tends to empty their fuel tank quicker same with EV, they tend to run the battery out faster or range reduced faster as the faster you drive an EV and higher current the electric motor requires and the more battery voltage drops. A range at 30mph is much longer than at 80mph. I would point out that EV range is also weather dependent (temperature affects battery chemistry, rain/snow road condition affects traction and in turn affects range as well). Newer battery management systems has mitigations for temperature control etc so it's less a concern.
- You have to be mindful about your road trip planning and charging station locations. This is the same for ICEs, but since gas stations are everywhere in urban areas so it is not a concern. It sure will improve for EVs as we build out charging infrastructure. U.S. regulators were able to negotiate a deal with VW for its diesel gate settlement so VW is contributing hughly in building out charging infrastructures.
- DC Faster charger's reliability. As an early adopter of EV, I felt this pain first hand. The early 400V DC faster charger prioritize safety and hence it gets tripped up and disconnect the charging circuit a lot. But I am seeing less and less this happens in recent years, so I'd say it's only getting improved.
- Charging etiquette. I suspect this is similar as ICE. When you refilling gas and getting some snacks and run for a bathroom break, do you park your car right in front of the gas pump even though it's fully refueled? You probably shouldn't right? Same with using DC faster chargers. Don't squat the charging spot if your car is fully charged and or above 80% of charge (above 80% charge it automatically switch to a slower charging rate), let the people inline to use the charger.

Newer battery management systems has mitigations for temperature control etc so it's less a concern. The annoying thing here is that the range planners I've been using (Teslas and abtterrangeplanner) cut the charger distances really close on some common routes I've checked - like reaching the charger at < 15% charge. Which, at least for me, seems like a heck of a close call for a situation where road traffic conditions, temperature and possible detours can quickly burn away that remaining battery.
