Bloomberg did a survey of 5000 Tesla Model 3 owners
Here are some highlights
(And these are very impressive numbers)
The scale is 0-5
Those Tesla owners who haven't charged at a Super Charger yet are probably the "neutrals".
It should be noted that Bloomberg isn't a big fan of Tesla, and as such, some of the data points in the "Very Dissatisfied" and "Somewhat Dissatisfied" categories didn't belong there based on the comments that accompanied the survey submissions (I got to read some of these comments, that's how I know this). So the Model 3 does even better than these charts would indicate!
