In this scenario, could the behaviour of the scooterist approaching the intersection constitute a hazard?

In the video you are driving through a housing estate on a priority road (sign D-1) and approaching a junction; on the pavement on the left, a person in a red jacket on an electric scooter is riding towards the junction, and a minibus is waiting on the minor road. The behaviour of the scooter rider may be a hazard. The answer is: yes.

The Road Traffic Act requires a driver to be careful, and when approaching a junction - to exercise particular caution, and allows you, under the principle of limited trust, to be prepared for unusual behaviour by others when the circumstances suggest it. A person on an electric scooter riding along the pavement straight towards the junction is exactly such a circumstance: they may ride down onto the roadway without stopping in order to get to the other side, cut across your path, or ride onto the roadway of the side road right in front of the minibus, whose driver will not be looking at them when moving off. An electric scooter is quiet and fast and has no indicators, and its rider often does not look around before riding off the pavement. That is why, despite having right of way, you take your foot off the accelerator, watch the scooter rider until you have passed the junction and are ready to brake.
