Plenty of people that can afford them and that would likely benefit are not buying them because of preference.

In many cases, this is rational. Yeah, a used Model 3 with a great rate plan is probably worth it as a commuter, but what if you are an outlier? Even a low battery failure rate can be a risk, and extended warranties are expensive.

But also, some of it is irrational, as the FB comments effectively feed many false fear driven narratives.
