What like New Yorkers are good drivers? Pshhhhh please. They can't merge if their lives depend on it. Diagram time:
Red car circled in flamboyant green... these cars... I'd say.. more often than not... will SLAM on their brakes due to oncoming blue car. Blue car stays in it's own lane, as shown.. It merges eventually.. like a quarter mile down the road. But here at the intersection, red car in circle of flamboyant green causes backup and sometimes accidents (Large Hummer behind it, as shown)... The merge of the blue car, doesn't have a yield or even a light, as they're always staying in their lane..
But people love to slam on their brakes (red car) because of the blue car... WHYYY? They have their own lane. I know their being cautious... but it's worse when cars slow down in the middle of an intersection like that.
We're not called Massholes because we can't drive. Because we drive like dicks, maybe....
We can (usually) merge and follow signs... usually...
BTW I vote this diagram of the year.
