Cross-posting from over on the official forum:

Leave it enabled ("On") by default, but please, for the love of the gods of immersive exploration in virtual open worlds, let us decide if we want to just follow the obnoxious pulsing thing like mindless sheep or figure out where to go and how to get there ourselves.

Let's look at an example:

Alright, the Telecom Tower it is.

Switching over to the map, and having a look where that Telecom Tower might be, relative to our current position.
Looks like it's not that far off to the south-west and we're already facing in the more or less right direction when we would leave the garage/workshop.
Just have to take a turn right, then left again and straight ahead.

Switching over to V in the car again, we appear to have deduced right. There it is.
Looks like a telecom tower indeed, and it's rather close to our position, so it must be the one.
Alright, let's go.

No, no, no... STOP, stop right there, clueless gamer who can't think for her-/himself.
You NEED hand-holding, even for this seemingly trivial navigational task, for you surely might get lost and die or something. Believe me, it's only for your best.
Here's a convenient pulsing yellow thing for you to follow, pay those vistas and environments no mind. And forget about that stupid map. Maps, cardinal directions and stuff is for nerds and losers.
Just FOLLOW the pulsing yellow thing, FOLLOW it and everything will be alright...

someone claims he can disable it with Z but it seems to not work for anyone else

Not even with the unmodified standard key bindings, at least here on my end.
Curious.

Having arrived in the city I realized there's a crap ton of other indicators cluttering up the screen, in addition to the already unnecessary objective marker.
If CDPR (hopefully) considers expanding HUD/interface customisation by adding the proposed toggle for the objective marker it should ideally cover those other icons (like the "gun" symbol or the "knife" symbol indicating vendors) as well.
