Police were made aware of this video a day later and began investigating.
It now appears there were two incidents involving the same driver.
This surely demonstrates that the first incident was not accidental. Instead, the driver seems intent on causing alarm and/or injury.
ACT Police have now released the images on this page (at top and below) of both incidents.
They are seeking the identity of the two motorbike riders involved and have released this statement:
About 4:30pm, the riders were separately travelling northbound on Majura Parkway, Majura, when a green Ford Falcon swerved, almost colliding with the riders. At the time, the riders were lawfully lane filtering.
If you are one of the motorbike riders affected please contact ACT Policing on 131444. Please quote reference 6327970.
Police are also urging anyone who knows the motorbike riders or who witnessed or has dash-cam footage of this incident to contact Crime Stoppers on 1800 333 000, or via the Crime Stoppers ACT website.
Please quote reference 6327970. Information can be provided anonymously.
ACT Police have confirmed they will alert us on the outcome of their investigation into these incidents.
