Don't forget to throw pennies at someone who just smoothly merged in sparse traffic; while passing them (and everyone else on the highway) on the ramp. When you reach the end of the ramp, it is customary to wave an RCW printed on a flag out your driver's side window.

This is how entire column of traffic between Bellevue and Everett knows you'll be introducing a ripple by forcing your merge in front of someone who is surprised, confused and possibly angry because they had accelerated a bit to give you a spot behind them, but no, see, the engineers, the RCW's. It was the wrong spot.

Now slow the full column down to 65, after it just slowed down to 65 to politely let you in and had already started back towards that classic +4 miles per hour cordial American cruise.

Then make a post about what civic engineers intended even though you've never met one, quoting an RCW, even though you have no interest other than to prove the Bad People Who Are Both Not You And To Blame wrong.

Not that you'd ever research it, or you'd find strict zipper merge is meant for gridlock when moving into traffic is like taking turns parking in a pet dispenser, NOT in sparse traffic. In this context it makes sense because it reduces time hesitating over who is making a decision, while also allowing more cars to queue.

That's the funny thing, you all talk about the road capacity like literally those three cars are breaking the city's back. That's not the point of zipper. The point is to avoid what makes 4 way stops slow.
