Mostly Harmless
Anecdotally, but everyone I speak with that isn't very EV-experienced, has the following complaints:
1. Range - for some reason they believe they need 1000km range for no reason
2. Battery replacement cost which they take as a given after a certain number of years (6-8-10)
I think offering some way to alleviate concern #2 would go a long way for a lot of potential customers. Even if it is something like a guaranteed replacement price of 5000$ that can be spread over a number of years. This would remove all the fear mongering that the media loves to promote.
Another approach could be making the facts about battery degradation and replacement on currently offered models (among other things) easier to find when considering an EV.
Seems like I've seen data for busting EV myths on some .gov websites and from other trusted third-parties which could be convenient links to have in an FAQ section for all EV manufacturer's websites, and as part of ad campaigns.
