Answer :
Final answer:
The 'Identify' step in the IPDE driving strategy becomes more difficult on expressways due to higher speeds, multiple lanes, and heavier traffic that mandate quick processing of extensive information and accurate identification of potential hazards and road conditions.
Explanation:
In the IPDE (Identify, Predict, Decide, and Execute) strategy utilised during driving, the step that becomes more difficult on expressways as a result of higher speeds, multiple lanes, and heavier traffic is the 'Identify' step. This is because drivers need to process a lot of information very quickly and distinguish potential hazards and road conditions while going at high speeds on the expressway. This is especially challenging when there are multiple lanes and heavy traffic as it requires greater concentration and quick reflexes.

Final answer:
The 'Decision' step of the IPDE (Identify, Predict, Decide, Execute) driving strategy becomes more difficult on expressways due to higher speeds, multiple lanes, and heavier traffic. These factors require faster reactions, more complex visual scanning, and can introduce a higher level of uncertainty.
Explanation:
The IPDE step that higher speeds, multiple lanes, and heavier traffic make more difficult on expressways is the Decision step. The IPDE process stands for Identify, Predict, Decide, and Execute, which is a strategy used in driving to anticipate and respond to situations on the road. Higher speeds require quicker reactions, and more lanes means a greater area to monitor. Additionally, heavier traffic brings uncertainty due to the increased number of vehicles whose actions you need to anticipate.
For example, when driving at a high speed, your window to detect a hazard, decide on an action, and execute that action is significantly reduced. The presence of more lanes adds to the complexity, as you now have more areas to visually scan and more actors to predict. Finally, heavy traffic means more potential uncertainties, such as sudden lane changes or hard braking by other drivers, requiring more complex decisions.
