Dashcam footage captures bus crash - but who's to blame?

Social media is divided over this footage, captured on dashcam by an HGV driver and released onto the internet. It shows the driver of a Mazda saloon attempting to cross a junction – but being hit halfway across by a double decker bus.

The footage, captured in Kingston upon Thames, shows the HGV pulling up to a junction and stopping, while coming from the opposite direction, a black Mazda does the same. The car slowly moves across the junction, while the driver waves his thanks at the driver of the HGV.
