Is a vehicle travelling at high speed more difficult for other road users to notice?

The question is whether a vehicle travelling at high speed may be more difficult for other road users to notice. The answer is: yes.

The Road Traffic Act requires you to drive at a speed that ensures control of the vehicle and is adjusted to the traffic conditions, and one of the reasons is how others perceive your speed. A driver coming out of a minor road, a pedestrian at a crossing or a cyclist judge whether they have enough time on the basis of distance and of what they are used to in terms of typical speeds; a car travelling much faster than others is far away at the moment they look and seems safe, and a second later it is already close. A fast vehicle also stays in the field of view for a shorter time - it may be hidden by a bend, a hill, a parked car or a pole exactly at the moment when someone is checking the road, and at high speed it is harder to judge its distance, especially at night when only its lights are visible. That is why speeding increases the risk that someone else will make a mistake, assuming they have time - and even if part of the blame falls on them, the accident affects both of you, and by speeding you are also responsible, because others have the right to expect that you are driving in line with the rules.
