AI interface / voice assistant

We are living in an AI age, or at least starting to live with AI.

I do not know ANY navigation, not even Google Maps (ok, some rudimentary commands...), which is able to be widely controlled by speech commands during navigation. Ok - some car navigation systems are trained to input and find a destination, but this is all?!

I need to add a waypoint during navigation, delete the next waypoint, add a refilling station, a charger on the route (and not besides the motorway or on the opposite lane). I want to re-navigate due a road contruction site just ahead of me.

Some points require a higher level of intelligence, ok, but most systems, do not even have a simple interface to the operating systems, wich allows a voice assistant or AI to do things! Why is all this so old-fashioned?

I’ll give you an example: when I drive my smart #5 in smart pilot mode (level 2), it warns me, that there is sharp turn ahead and tells me to slow down - while the car is driving (supervided by me) on its own!!! Mayx car then races at full speed into the sharp turn and would crash. If on board systems have this information, why the hell do they not interact?
