Police in Saxony-Anhalt, Germany have said that a file on Radim Passer, the Bugatti Chiron owner who filmed himself going 417 km/h (259 mph) on the Autobahn, has been forwarded to prosecutors.

The police department is “looking at the possibility of a banned car race,” the U.K.’s The Sun reports. If that’s the case, Passer could be facing up to two years in prison.

Passer filmed himself driving his Chiron last summer on Germany’s famed Autobahn. A video of the run was released late last year and the driver claimed that he took every possible precaution to make the stunt as safe as possible, choosing a straight bit of road with good visibility.
