Compare the densest parts of Carmel to the densest part of a suburb of similar size and distance to its city Huddinge:
Carmel: https://www.google.ch/maps/@39.9641636,-86.1445548,1732m/dat...
Huddinge: https://www.google.ch/maps/@59.2347134,17.986286,1277m/data=...
The most noticeable part is that Carmel has way more roads and parkings. This is due to its bad public transport, notice how Carmel lacks a train station. Also if you look closer you can see that Huddinge has tens of bus lines running through covering most of this area (they are shown in Google maps), I can't find a single bus line in Carmel.
Another thing you can notice is the diversity of buildings. In Huddinge you have small dots of dense housing near its public transport/shopping hubs, with lots of freestanding houses filling the gaps. In Carmel on the other hand all of the places which would be filled with free standing houses are instead taken up by parking lots. In order to find any freestanding houses in Carmel you have to get further away, far enough that it is no longer within walking distance to any public hubs forcing them to take the car, which is why there are so many parking lots and large roads instead of houses in the center...
