Website ‘The Hill’, which reports news from the Senate and the House, has published an article on the fact that while autonomous vehicles are rapidly being developed America’s roads are simply not ready for them.
Poor quality paint is dangerously and very frequently used for pavement markings and crosswalks in the USA, in place of more-expensive but vastly-safer thermoplastic materials which have a high-glass-bead content for excellent reflectivity at night and in bad weather.
Compare the photo above with the one below. They are at the same location and were taken less than 12 hours apart.

According to Autoblog, university researchers “have figured out how to hack self-driving cars by putting stickers on street signs.”
Removing or alternating passing/overtaking possibilities on undivided rural highways, together with the introduction of narrow-profile guard rails between the center lines is a technique that was pioneered very successfully by Sweden and has now been used with similar success in New Zealand. And there’s definitely both the scope and the need to use it in the USA, too.
In pursuit of Vision Zero, LA is introducing what California (and the USA?) is calling scramble crosswalks, at which all traffic is stopped simultaneously while pedestrians can cross the intersection in any direction, including diagonally.
In surprise and great dismay, I nearly spat my mouthful of coffee all over my keyboard when I read the article More traffic experiments planned in Fayetteville a few minutes ago, from the Fayetteville Flyer.
Traffic circles, of a sort, were allegedly first built by the Romans in order to expedite chariot movements at busy intersections 2,000 years ago. Some countries still use basic traffic circles and if you are an adrenalin junky, go to Paris and try driving on the one around the Arc de Triomphe when vehicles are flowing thick and fast! However, what today are properly called “modern roundabouts” were invented half-a-century ago in 1960s Britain.

This is one example of a clearly very useful, interactive traffic sign (from Britain) that I have encountered recently.
Not only does it warn drivers who are travelling too fast for the location but it also warns of vehicles emerging from an upcoming junction / intersection where fatal crashes have previously occurred.
