I think 125 miles of actual range would help out. Actual range with heat/AC and highway driving, without worries about degradation. In other words, what Tesla did with the RAV4.
Now, keep in mind, I live in the land of conservatives and big oil (and I get my paycheck from big oil), so I don't pretend to know how people react to EVs elsewhere. But when I mention to people that I want an EV, I get the following reactions:
1) That's crazy
2) What are you going to do when you run out of juice
3) How are you going to take a road trip
4) That's crazy (variation)
5) That's strange (variation)
6) Too early, unproven technology, etc
7) I didn't know you were a hippie (honestly, I have heard this a few times)
Almost no-one asks relevant questions. They are dismissive, not interested.
It's very disheartening. I want someone to share my EV enthusiasm with, in meatspace, not just online. I can explain all day that I've never run out of gas, live well within the range constraints of current EVs, have an ICE vehicle for road trips, and all the advantages of having an EV, but people still write it off as strange and/or crazy. I don't think that particular perception of EVs is likely to change around here until long range EVs (250-300 miles) become common and affordable, AND there is charging infrastructure that can dump a LOT of range quickly into the vehicle.
I am fortunate that my wife doesn't think it's crazy. She finds it intriguing. I think as long as I get an EV that is the right combination of affordable, practical, and reliable, she'll be on board.
Also ... What's up with L2 chargers going in at places like Walgreens in the middle of nowhere? If I need to spend several hours filling up my electron tank, why not put the EVSE somewhere people might actually be inclined to hang out for 2-4 hours? You can't do 4 hours of shopping at a drugstore. I can understand the L3 chargers at these places ... that's actually useful. Why aren't there any along the highways? Why do I have to pay $89/mo to access them? It's ridiculous. Again, I understand the picture is not the same in AZ or CA ... That's just my $0.02
Anyway ... 125 miles of minimum and lasting range would help around here. It would enable trips to Galveston without waypoint charging. And some fast chargers along the corridors would make trips to other cities pleasant.
