Personally I used to drive by sidelights quite happily but the new street lights are far more spotlightly and have much less spill on to the road. They're fine for pedestrians they're not great for unlit objects on the road.
But its not about looking our for unlit objects its about insufficient lumens to pick out people amongst the flood of badly configured overly powerful headlights on modern (mostly German) cars. And while pedestrians may not be shamed for not wearing headtorches, there is plenty of suggestion that runners need be light up like christmas trees (on here too at times) and the tragic situation where kids are covered in high vis when ever they leave the school.
