I passed the California driving test this afternoon, now the streets are no longer safe :-)
The interim driver license looks really shabby, it's just this text printed on cheap copier paper:

                        INTERIM DRIVER LICENSE

                REGISTRATION, OR PUBLIC BENEFITS.

Also the driving test itself was more like a joke than a real test. I just had to drive around for about 10 minutes. No highway driving, no complicated intersections, no 'advanced' maneuvers, no real parallel parking. In fact the "parallel parking" part was to pull over to the curb and drive backwards 3 meters (w/o any other car around of course). And the most complicated maneuvers were to change lanes and to make a left turn at an intersection.
