I think Tesla and BMW(?) incorporate range estimates into the navigation system, which does exactly what you propose.
There are smartphone apps that can do similar. As for the Bolt, I can't speak for more recent models, but my 2019 doesn't have a Navigation system, I don't even think it was an option. It can, however, display the navigation screen from a connected (Android or Apple) smart phone. It also has the ability to show you charging stations that are (probably) within your current range and I believe that takes terrain into account. FWIW the Bolt range estimator takes into account recent trips, battery loads, and I believe current speed/efficiency. So if your AC/Heater is on it will show a range that can be upto %25 lower than if you turn it off. Well, 25% in my experience, I'm sure if you're somewhere really hot/cold, then climate control can have a bigger impact on range.
