Which is of course a quite sane assumption given that 80% of the people on public roads are bad drivers and/or not paying attention, and 80% of the remainder is a bad driver without realizing it, and is quite vocal on online forums about robots telling them they're wrong based on logic and physics
I just don't know about this. It's difficult to say what a "good" or "bad" driver is, unless you were to, say, document a long list of behaviors that have X probability for an accident, weighted by severity, and then follow every driver around for a statistically significant amount of time, in order to evaluate if they are better or worse than average. Then, you'd have to evaluate whether or not Tesla's driver aids were making improvements on those activities, and to what extent.
In other words, it's not really measurable in any practical sense. Hence the moral conundrum. We all want self-driving cars to be better than humans at driving. But it's not really possible yet to say if these driver aids are a step in the right direction or not.
Assuming we're all a**holes is fine, but without any information to say whether the technology is making us better, we will just end up arguing. Really your perspective just reflects whether your null hypothesis is "any new driver's aid is better" or "any new driver's aid is likely worse".
Like, I've been driving for 25 years, probably hundreds of thousands of miles in many environments, on several continents, never been in an accident, never gotten a speeding ticket or other moving violation, fairly competent advanced-group track day driver, done a bit of wheel-to-wheel racing, etc. But none of that proves I'm a good driver or a bad driver. Maybe I've just been lucky and attribute it to skill. Maybe some of these aids would actually make me better. Or not. But nobody can say at this point. So all we have is this - arguments about our ideas and feelings about the technology.
