Respectfully, Yuh.Naw.
You can use any mode based on conditions and your preferences.
I use tow mode but not exclusively.
You probably will NOT want tow mode in stop n go traffic, parking lots, or campgrounds for example.
Funny how you say stop n go traffic because that's specifically where I had my issue. I got fuel and forgot to put it back into tow mode. Going through town ate up my battery and the first hill out of town was after a stop light I didn't have enough acceleration because of the dead battery and held everyone up while I just had to listen to the engine scream doing nearly nothing.
The condition is towing and the preference is the ability to drive at a useful pace.
