Has anyone surveyed EV buyers on what almost stopped them?

Yes, post-purchase surveys work really well for this — buyers are past the anxiety so they open up more honestly. We ran one last year using a simple Likert scale around 8 common barriers (range anxiety, cost, charging access, etc.) and got really clean data. Tools like Typeform or even a quick Qualtrics setup work fine, just make sure to recruit through the dealer or registration data if you can.
