This is one of the reasons I predict that the Model 3 will have a hard time coming in under 4,000 lbs curb weight. The Model S60 RWD might get down to 3,800, but the more features like these I see, that might be a stretch.
I agree that GM does need to start offering these as an option, but I doubt that people like me would care much (or pay for it).
We can talk until we're blue in the face about whether the Bolt EV and Model 3 are competitors. While the capabilities of the cars are very similar, which makes them comparable only because they are both EVs, the brand, image, and accoutrements are very different. And they appeal to very different audiences. It would be a mistake for Tesla to use the Model 3 to chase the same customer market that GM is targeting with the Bolt EV. And it would be a mistake for GM to use the Bolt EV to chase the same customer market that Tesla is targeting with the Model 3. So as much as we want to debate features, the two cars aren't really in competition with each other.
Heck, for some people that walk the line (myself included), they are interested in having BOTH the Bolt EV and Model 3 in their driveways. Maybe I'm biased in that regard, but that is why I always saw the Model 3 as a potential replacement for our Volt (not our C-Max, which the Bolt EV replaced). Now to that 200 mile EV 4x4...
