I am unclear why regulators haven’t taken aim at this for safety reasons given how regulated every other component of a vehicle is. Same with the digitization of the dashboard, which is a massive distraction while driving. And at the same time, height of the front hood - why haven’t regulators had anything to say with trucks having hoods well above the height of many pedestrians?
