Final answer:
Drivers often perceive motorcycles to be smaller due to their size and distance, but appearance can be deceiving.
Step-by-step explanation:
When drivers see motorcycles on the road, they may perceive them to be smaller than other vehicles due to their size and distance. However, it's important to keep in mind that appearance can be deceiving. If something is far away, it will appear smaller, even if it is actually the same size as other vehicles.
