Ok, this has to be some sort of record:

[Brenton Alan Erhardt, 39] was pulled over by police on the Stuart Highway in July speeding at 147 kilometres per hour, south of Daly Waters.

He admitted to officers he filmed himself masturbating while driving from Adelaide to Darwin.

He also pleaded guilty to driving unlicensed, carrying two cannabis smoking pipes, administering the drug and carrying a loaded rifle.

Ta-da!!!
