> Speed is the most dangerous aspect of motor vehicles
Speed difference is dangerous. So yes the difference in speed between vehicle and stationary objects it can hit (trees, poles, parker cars). On highways without a divider the danger is from incoming cars as that will double the impact speed. On highways with dividers having speed different from cars around you can be dangerous because it means you are changing lanes often else others are changing lanes to get around you.
