Why should you avoid driving next to other vehicles on multi-lane roads?

The reason to avoid driving next to other vehicles on multi-lane roads is primarily related to safety concerns associated with potential lane changes and other driver behaviors. When you drive alongside another vehicle, there is an increased risk that the driver of that vehicle might inadvertently drift into your lane, especially if they are distracted or not fully aware of their surroundings. This situation can lead to accidents, as there is less space to maneuver and respond if an unexpected lane change occurs. Keeping a safe distance from other vehicles allows for better visibility, reaction time, and space to avoid collisions, thereby enhancing overall road safety. Other choices may touch on different aspects of driving but do not address this specific and critical concern as directly.
