TomTom has better traffic information, way better guidance on complex roads (google maps will tell me to take the exit, and it small font it says 2400m, which is the next exit). It has better traffic cam warnings, shows max speed more reliably etc.
But also it is slow and clumsy to search for a destination, especially if you do not have the exact address (like a shop by name).
As I have practically unlimited data and good coverage everywhere I go, offline maps are more of a drag than a plus. Just saw amigo mentioned, will check that out now
Google doesn't make Maps because you pay them for it, but because they want to know where you are, where you're going and how long you look at what. So they're not going to care much about how well it works for you without an internet connection, and the offline map probably only exists to check the checkbox and stop people from going to the competition.
- The offline experience is garbage. Default behavior should cache large routes offline immediately when I’m on WiFi.
- partial connectivity experience is garbage. Stalled map loads, freezes, etc while driving through a 1x cell service area, even if map was pre-downloaded.
- ads for places I don’t care about.
- unable to automatically show places I do care about.
- searching for exits sucks
- searching for rest areas sucks
- measuring distances requires interrupting the navigation
- no way to view current speed, elevation
- filtering for restaurants with drive throughs very frequently ignores the “with drive through” part of the query.
- gas prices come and go on gas station display. No way to filter on price.
- why in the world can’t we filter based on restroom cleanliness?
- trailer towing friendly parking lots?
- enter max range between drives, give me fuel stops optimizing for gas cost or cadence of stops. Mapquest did this in the early 2000s FFS and you printed out the result.
- overlay recent breadcrumb history on map without it getting blown away any time navigation is interrupted.
- search map without interrupting navigation in a way that doesn’t assume something should be added as a waypoint. (Sometimes people use phones for more than one thing at once on a 12 hour road trip.)
The list goes on and on. There are like 4 use-cases that work with google maps and they are all for basic users and nothing else.
