What I've noticed on car forums over time is its gone from not liking Tesla because they are pure EV to wanting other EV's to succeed to assist in the demise of Tesla!I agree 100% with Stirfelt's assessment. I can't go a week without seeing a report (or multiple reports) about Tesla going bankrupt. And it's been that way for a very long time. And yet, Tesla is still going, against all odds.
I think part of the hate is not always because people don't like EV's its some of the Tesla fanboys that have turned people off the brand. In many ways Telsa are very much the Apple of the automotive world. People who are 100% exclusively locked in to the Apple ecosystem (regardless if there is better options) can be quite annoying, close minded and are definitely apologists for bad decisions and sometimes sub par products...lets be honest we see some of that behaviour on here.
I think my Model-S is a brilliant car and of all the vehicles I own I look forward to driving it the most (mainly because of the performance). But it has its fair share of issues that I grizzle about and unfortunately I would say are also never going to be resolved with the way the company is run.
