How should a motorcyclist select their lane position (Left / Position 1, Center / Position 2, Right / Position 3) within a single traffic lane?

1. Remain permanently glued to the extreme right curb under all circumstances, even when turning left
2. Weave continuously back and forth across all three positions at high speed to entertain other motorists
3. Ride exclusively on top of the dashed white lane dividing line between lanes
4. Dynamically adjust position to maximize forward visibility, maintain space cushions, avoid vehicle blind spots, and present a visible profile to other drivers
