Traffic (the book) says most Americans merge into traffic wrong when lanes reduce (from say 3 lanes to 2 lanes for example.)
The right way is waiting until you are at the very end of the lane that's reducing. When that happens up to 60% more cars per hour get through the bottle neck in heavy traffic and accidents resulting in killed or serious injury are reduced by up to 80%.
Bottom line having multiple entry points in a queue with multiple slow down points due to the multiple entry points is the cause of the reduced performance with the way most Americans do it.
Not riding peoples ass and leaving room would make it smoother too.
Agreed! Though the book says multiple studies find people who leave 2 seconds or more are more likely to rear end someone. While the studies didn't identify why it was hypothesized people who most often leave 2 seconds practice distracted driving. I know the last time I was rear ended my rear dash cam clearly showed he has 200+ feet and didn't look up from his phone until right before he hit me.
Thats probably more of a correlation though. Like, the drivers that leave that much space are probably doing so only because they know they arent paying attention. If they were paying attention, a 2s distance would be safer.
