Not only 50k for driving while bule. Just being in a car with a local also merits the 50k. I was out with a couple of associates, and got waved over (this was in Jakarta, however). My Indo associate got out, and after a few minutes he came back 50k poorer. Seems like it's the standard "on the spot" fine.
