What if there is an active skill you could do (with the requisite skillset) to blend into traffic. You would still have to advance a room at a time like normal, but would add a fun benefit of traffic, both to crime and incognito driving about and blend into the masses.
In general would be like sneak, but maybe the traffic messages of "A red van driven by x' would be replaced by the hidden vehicle, giving incentive to pay attention to both who is blocking traffic and a fun cat and mouse game going down the tube.
Fully understand if this is both impossible game system wise or something that SD doesn't want in it, just an amalgamation of things in my mind I just wanted to jot down somewhere.
