So? What you're telling me is that you've experienced people who are afraid of a new thing. That's not a reflection on the merits of the new thing, that's a refection on the irrationality/complacency of the people you're talking to.
They don't think about the issues when buying the ICE because they've already come to accept the ridiculous compromises they have to make. They accept that they are leashed to gas stations, they accept that they have to waste time and money there instead of filling up for almost nothing at home while they sleep, that they might have to stop on their way to work and be late or from work when all they want to do is get home because they forgot how full their car was, they accept all this ridiculous nonsense because "that's just how it's always been." Just because they don't think about it doesn't make it any less ridiculous. There's so many compromises associated with driving on gas which do not exist for electric.
This software update is not particularly important to many owners, except as has been mentioned the people whose wives have problems with doing the math on where they're going to need to charge or whatever else (*not intending that to be sexist, just pointing out the specific example, I think it was AlMc?). I can see how it would be important to easing the anxiety of people who are thinking of owning the car, since you can tell them "the car will do it for you" instead of "it's easy to plan these things yourself." But I still think the entire concept of range anxiety is silly, and the idea that ICE vehicles do not suffer from a similar phenomenon is flatly wrong. It's just fear of the new.
edit: another thought I haven't mentioned yet. It does seem like the new software could eventually grow in scope, because the car has access to a lot more data and control than it seems to be using. But I'm sure all of that will be added in the future. The car knows current outside temperature, current and past driver use of climate control (separated by profile), current speed, current energy use, topography of the upcoming highway, distance to the nearest charge points, approximate route, traffic, historical energy use on many roads, weather conditions, current supercharger use status, all kinds of things, and all of those could be put together with cruise control to have the car automatically choose an optimal speed to get you to where you're going. It's my understanding that it doesn't set the speed for you or anything, it just tells you the places to stop. Which is fine, but I can see it growing into more over time. That said none of this is that exciting to me since I can already do those calculations on my own and am fully comfortable with them. But I guess it would be useful for some customers.
