@how.stuff.happens: The driver who merges at the last second is doing it right 🚧 #zippermerge #traffic You merged a mile early like a polite person. Then someone flies up the empty lane and cuts in right in front of you. Rude? Plot twist: the late merger is doing it right. 🤯 When everyone merges early, one lane sits empty. Half the road is wasted, so the line stretches back twice as far, and all that squeezing in makes people brake, which sends a stop-and-go wave back down the line. The zipper merge fixes it: both lanes stay full all the way to the cones, then cars take turns, one from each lane, like a zipper. Minnesota's transportation department (MnDOT) studied the late merge and found backups can get up to 40% shorter, and both lanes move at the same speed, so nobody is cutting anybody. One catch: it only works when traffic is already slow. On an open road, merge early. Still merging a mile early? Defend yourself in the comments. 👇 Tag the friend who never lets anyone in. (Also, watch for the tumbleweed.) #zippermerge #traffic #driving

Cars merging late slows the entire lane down. He’s not doing it right.

Sadly not everyone knows the zipper rule. and no one is going to bother to learn it. id rather merge early. then I don't have to sit for ages because everyone wants to not let me in

Geeeeeeeee :
The amount of people that get mad at me for zipper merging is insane. But I know I’m doing it right so they can get mad all they want. It’s weird to let a stranger affect your mood so much. Just let the person in and move on with your life 😅

Zipper merge only works on paper.

The problem is that you can’t trust anyone to do it right

The thing that this doesn't take into account, a zipper only works properly when 1 tooth goes at a time. When 3 teeth try to fit in the same spot, the zipper no longer works.

If everyone did this it works. The issue is if you alone do this you get stuck hoping someone lets you over. Personally I trained myself to look for the sign before and I merge before the traffic even starts slowing. When I have to merge last minute I always wave a thank you to who let me in. Because they could choose not to and make it dangerous. I don’t expect anyone else to do this but I’ve driven a long time over 28 yrs without a single accident or ticket. I’ll keep being borderline paranoid not to deal with that hassle or out myself or my daughter in danger.

Why would you leave a mile of unused space, merge early if you prefer but I am going to use the empty and not cut any one off but.

That's not at all how it works in real life friend. the backup is caused by people trying to merge the way you indicate

What? Meanwhile now there’s 2 lanes of traffic because they refuse to merge over or look down the damn road. There’s a reason the signs start telling you to merge a mile away

zipper merge doesn't work, it takes longer because people cannot merge. and to add all merges is meant to be a zipper merge

nobody will do it, let alone the entitled people! Sorry, but I am in line and I am not letting you in. If you pit your signal light yes, but if you have no signal light you're not getting in. Ask politely and you'll get what you want.

wrong. everyone going up the wrong lane causes a brake when they cut in. everyone that merges early are traveling a consistent speed, plus it's very rude to think your to good to wait like everyone else
