It's another clickbait article about roads with no intent but to rile people up
You are correct about uncontrolled intersections, this suggests we could remove the separate pedestrian signals at traffic lights
As shown in the image: "Pedestrians walking the same diection as main road traffic share the same green light"
As you say (and included in the article) there's a stunningly obvious reason we don't do this already: pedestrians are vulnerable, and we can make good estimates about how long the pedestrian red should be to allow safe crossing
Just put 'making intersections less safe' over there on the garbage pile with 'speed has no impact on the likelihood or severity of accidents'
