I found in my own amateur UX studies that there are drivers who hear "in a quarter mile, turn right" and don't know how far that is, even after having heard that prompt thousands of times. You'd think that after a while they'd build a mental model of the distance. Instead, they seem to just tune out the "in a quarter mile". This is one of the classes of users for which products need to be designed. (I have similar problems with people's heights.)

Also, as a passenger it's fairly easy to say "turn in five blocks" and track how many blocks are left, maybe even while holding a conversation. For drivers, that seems more difficult, probably due to cognitive overload, unless it's just a couple of blocks. And I've noticed that some drivers react to that kind of direction by scanning the view and quickly translating the number of blocks to a landmark.

Which is of course region specific. Using it in the UK would be confusing as (often) the roads just aren't laid out like that, and "in X blocks" is almost never used.

I’m in that camp where I hear the “in X units of measure turn right” and get confused as I can’t really relate to that when driving vs walking or reading a map — which is the entire reason I’m using voice prompts with the app.

Part of the reason is that my frame of reference in a fast moving car is time and not distance. How many feet Is that car in front of you? Unless it is under 10 mph and under 20 feet I have no idea. I do have some idea about how many seconds it is as I have to know that in order to avoid the car if it stops working quickly.

I don’t know why the apps don’t say “in 10 seconds turn right” or maybe “turn right now!” With an emphasis as that’s how I’m used to getting directions from a passenger.

I'm pretty good with navigation and directions, but those directions become useless for me once the app tells me anything in feet/meters. Once I hear "In 300 feet..." I stop listening and glance at the spatial layout of the roads.

Oh yeah I love when people measure turns by the number of intersections to pass. Things like quarter mile or 1000 ft are hot garbage for me in terms of understanding how close I am to needing to turn, since it depends a lot on how fast I'm moving.

Yeah, I don't understand why mapping software doesn't just say:

* after the next 2 intersections, turn right

* after the next intersection, turn right

* turn right at the next intersection

* TURN RIGHT NOW

* you missed the turn right, ....

Other huge annoyances:

- Not telling you which lane it is optimal to stay on on multilane roads

- Not telling you which road signs to follow outside urban centers via voice

- Not telling you about speed limit changes

In general, I find the guidance to be barely usable instead of being excellent as it could be
