Using the 'RiderRadar' system, anything is considered immediate if it is within how many seconds of you?

The 'RiderRadar' system emphasizes the importance of being aware of immediate surroundings for the safety of riders. Recognizing something as 'immediate' if it is within four seconds allows the rider to react promptly to potential hazards. This time frame considers the average human reaction time and the speed at which motorcycles can travel.

Understanding that four seconds is the standard for assessing the immediacy of a threat helps riders maintain better situational awareness, ensuring they have enough time to make safe maneuvers or decisions in potentially dangerous situations. The other options suggest shorter time frames that might not provide riders with adequate reaction time, particularly in dynamic or high-speed riding conditions.
