They mostly solved for that with our HOV lanes in Colorado. Some places you can’t enter or exit, some places you can enter but not exit, and others you can exit but not enter. Also merging with slow lanes instead of fast lanes. And all monitored by the people who charge for HOV lanes. Adherence looks to be pretty good overall.
Does the book mention that the Zipper merge is inherently flawed as it relies on drivers to be far more cooperative than they are?
Yeah. So, like communism, the entire theory breaks down when humans are actually involved.

Yes
Sadly, there are many places in Canada with the same problem. I blame Americans for that, too.
