A lot of them are being told this, and they just believe it without running the numbers for their use case. For some it would be longer until infrastructure improves, but for others it would actually be less time “waiting” on their EV than their ICE car. I’m in the UK and I’ve spent 0 mins waiting on my EV charging in the last 4 months. Plug in at night and unplug in the morning. I’ve also spent 0 minutes visiting gas stations.
America has bigger distances and there are other factors of course.
