Saarland state police said Friday the 35-year-old man was pulled over for doing 130 kph (80 mph) in a 100 kph zone while passing a truck Monday.
Built on a wooden frame on his passenger seat they found a laptop on a docking station tilted for easy driver access, a printer, router, wireless internet stick, WLAN antenna, and an inverter to power it all.
A navigation system and cellphone mounted to the windshield completed the array.
Since there was no evidence he used the office while moving, he got away with a €120 ($153) speeding ticket and a possible fine for having unsecured items in his car.
