Australia's leading science communicator, Dr Karl, talked about the traffic thing not long ago and surprise surprise, it's not the government causing traffic jams on highways, it's humans overcompensating for what's in front of them. Someone see's something that makes them brake a bit, say an animal near the road or whatever. That person slows from 100km/ h to 90 just in case. The person behind them sees them slowing down, overcompensates for safety and slows to 85. The person behind them does the same and slows to 80. This ripples on from car to car until the people at the back are barely moving and going why has everyone stopped?
So I guess the real solution is to ignore when other people use their brakes on the highway...
(I know I've used a lot of them but did I need the commas either side of Dr Karl?)
