Sometimes I like loading in with traffic, sometimes I like cruising solo. If I want to cruise solo, I don't like having to wait the extra time it takes to load in traffic only for me to delete it. A toggle button when selecting maps to load with or without traffic would be nice. Heck, it'd be really cool if it was level specific and remembered your choices.
You could select “Start freeroam with traffic” if you don’t want to wait during your game session and do it during your loading screen
I already have that selected, and always load in with traffic. My idea is essentially to take that button, and move it from whatever menu hole it's hiding in to the level select screen.
