For eco-drive enthusiasts, you could create a function that shows upcoming speed limits with an adjustable distance. For example, I would like to be informed about speed limits approximately 400 meters in advance, so I can deactivate the cruise control and let the car coast to the correct speed for the upcoming limit. For EVs, this would simultaneously involve regenerative braking, saving me fuel and brake pads. The environment would be cleaner, etc. Adaptive notification would be an advanced solution. It would use the g-sensor to understand my inertia and the speed difference from upcoming speed limits.
