Motorbike rider passes laptop through car window while driving

A ute driver has had a moment of pure luck after a keen-eyed motorcyclist spotted something suspicious on the vehicle's bonnet.

Video shows a motorcyclist look towards the ute while driving through Sydney's M5 tunnel in New South Wales.

Balanced precariously on the bonnet is what appears to be a laptop or an iPad.

The rider then leans over and grabs the device, using just one hand to keep the bike steady.

He successfully manages to pass the tablet through the vehicle's open window, neither driver slowing down during the process. 

The video was posted on reddit with the motorcyclist captioning, "riding to work, this guy left his work tablet on his car so I handed it over".
