How many maximum cars can be displayed on a PA5 TOD screen?

The correct choice indicates that a maximum of ten cars can be displayed on a PA5 TOD screen. This specification is critical for understanding the display capabilities of the system. The number ten is derived from the design parameters set for PA5 TOD systems, which optimize visibility and usability. Displaying up to ten cars allows for clear visibility without overwhelming the driver or the system, maintaining effective communication of essential information regarding traffic conditions.

In practical terms, having too many vehicles displayed could lead to cluttered screens, which might hinder quick understanding and decision-making for users. Therefore, the limitation to ten presents an ideal balance between providing enough information and maintaining clarity and usability.
