Here's one example of a complication.

Before I had the Feroza I would ride with Linston on personal business and we'd put the "off duty" sign in the window. After getting stopped by the police several times asking how he was "off duty" with a "tourist" in the car and having to explain and prove that we're related it just became easier to put the "chartered" sign in the window.

After that no stops for any reason
