I’m currently vacationing in a country where pedestrians are required to wear reflexive elements when it’s dark, and I really like that. However, putying all onus on pedestrians while not even analyzing the causes of crashes (including hit pedestrians and cyclists), which would lead to improved road infrastructure, signage and enforcement, will lead to more deaths. As long as you’re allowed to drive 80 km/h on a winding road where two cars can’t even pass each other, no amount of lights or reflective vests will save the pedestrians.
