IMO if you have to brake on the freeway, someone made an error.<p>Cool about brake lights; I&#x27;ve wondered for years why they don&#x27;t do this. I knew about some newer cars flashing the hazard lights in a very hard stop, but didn&#x27;t know any were doing brake light meters. Any idea which specific models? I&#x27;d love if they standardized the messaging across brands and countries; imagine a new mustang where 1 vertical bar on each side means light braking, 2 means moderate, and 3 + rapid flashing means very hard braking. Not sure what standard would make the most sense for this, but the sooner, the better, so new cars can adopt it. It&#x27;s way less useful &#x2F; less clear when each car does it differently.
