Ive seen lots of people excited about tesla stock. Some people who were already fans of their car seemed to buy into the hype but I haven’t heard any non-fanboy who has paid any attention to self driving say they expected this to work out.

The problem is that most people are not paying huge attention to self-driving and the marketing will end up causing some people to misjudge the capabilities and get them killed. At which point fanboys will move the goalposts to "it kills less people than humans operating cars", which I don't think is necessarily true depending on how you want to measure that.
