Why Jerk Drivers Who Merge at the Last Minute Are Actually More Efficient

Merging on the highway can be a fraught task. Most people do it the polite way: merging over into the lane as soon as possible, forming a polite line of people waiting to get off the highway or move out of a closed lane. But there’s always that one jerk who speeds ahead of the line of slowed traffic, merging into the lane at the last second possible and cutting ahead of the entire line of cautious drivers who merged a mile back. While we may resent those drivers, according to HowStuffWorks, this aggressive style of merging is actually the most efficient way to keep traffic moving.

The last-minute system, dubbed the “zipper merge,” suggests that all drivers wait until they’re almost at the fork in the road or start of the closed lane to merge over. Instead of creating a long line of cars at a standstill in the right lane, waiting until the last second maximizes road capacity, since cars are moving in both lanes. It also makes the road safer. Don’t believe it? Watch the principle at work in the animation below.

Traffic studies prove that the zipper merge is the most efficient way to keep a road moving. Instead of one lane of traffic whizzing by while the other lane slows down considerably, both lanes slow down slightly, and overall, the slowdown is more equitable across both lanes. According to the Minnesota Department of Transportation, it can reduce the length of backed up traffic by up to 40 percent.

But that assumes that every driver adopts the zipper merge. Unfortunately, it’s very hard to convince a whole society of drivers to suddenly change their behavior. Even if zipper mergers are technically correct, when the whole rest of the highway is operating under the belief that merging as soon as possible is the correct and polite way to go about dealing with a lane closure, that one guy merging at the last moment just looks like a jerk. The system only works if everyone plays by the same rules.

Some transportation departments have tried to encourage drivers to adopt the practice, putting up signs near road closures that ask people to “merge here,” nudging them to wait just a little longer before they get over.

Merging late may go against our very nature, however. Many people tend to “pre-crastinate,” according to one 2014 psychological study, trying to get a task out of the way as soon as possible even when doing so goes against our best interests. Penn State researchers found that when asked to complete the basic task of carrying buckets from one end of an alley to the other, people were willing to do more work rather than delay completing a basic task until the last second. Many participants opted to pick up a bucket closer to them, even when it meant they would have to carry the bucket farther, rather than waiting to pick up a bucket closer to their end goal.

So, it may be no surprise that the zipper merge hasn’t caught on, at least in the U.S. But at least now you can feel justified being that one last-minute merger.

9 Regional Pizza Toppings Worth a Try

Some people can become so devoted to their favorite specific pizza toppings, that many online ordering apps allow you to preset your preferences with the expectation they’re never going to change.

Granted, pepperoni and mushroom with extra cheese never fails to satisfy. But in honor of National Pizza Week (which kicks off today), try ordering one of these regional specialty toppings that might totally change your pizza perspective.

1. Truffles // New York City

Fall is truffle season, and New York’s restaurants and pizzerias love to take full advantage of the fluffy fungi to add flavor. As supplies are shipped through the city's artery of eateries, you'll find several locations that add the shaved delicacy to pies. Yelp reviewers are fond of Song E Napule in the West Village.

2. Lobster //Boston

It’s no great surprise that crustaceans who were occupying the coast just a few hours prior to being served are going to be a town specialty. But Boston does a great job of incorporating shellfish into their Italian-inspired fare, too: One of the most notable dishes is at Scampo inside the Liberty Hotel (and former jail), where chef Lydia Shire takes a thin crust pizza and douses it with heavy cream, garlic, and the meat of an entire two-pound lobster.

3. Provel Cheese // St. Louis, Missouri

If you think you’ve tried every possible cheese variety on your crust, you might have missed St. Louis’s proprietary variation: Provel, a highly-processed blend of Swiss, provolone, and cheddar. Gooey, waxy, and thick, it can be found at area chain Imo’s, which also doubles as the cheese’s distributor.

4. Crab // Baltimore, Maryland

While other area pie shops toss crab on their menu, no less an authority than Zagat declared Matthew's Pizza's crab deep dish pie to be well worth a road trip. It’s pizza so good that it helped fuel writer David Simon through a stint producing HBO’s The Wire. Simon once said "it’s unlike anything that calls itself pizza anywhere in the world."

5. Mashed potato // New Haven, Connecticut

New Haven was already renowned for its pizza before the proprietors of BAR decided to take the concept of comfort food to a new level. Their mashed potato pizza is topped with light, whipped spuds and bacon bits.

6. Salad // Los Angeles

It seems like a cliché: of course image-obsessed L.A. would spare calories by dousing their pizzas with lettuce. But looks can be deceiving. Grey Block Pizza in Santa Monica uses covers its dough with cheese, onion, and sour cream, which is then topped with a chopped salad, lemon-olive oil dressing, and a layer of fresh avocados. It’s thick, crunchy, and has no ability to spare your waistline.

7. Barbeque // Memphis, Tennessee

Barbeque chicken pizza is everywhere, but if you want it done right, head to Memphis and opt for the pork. Coletta’s—the city's oldest restaurant—takes a standard crust and drowns it in pulled pork and their signature barbeque sauce. The pies are so good that Elvis Presley kept a running tab he’d have Colonel Parker (his manager) pay off monthly. If you’re not local, they’ll be happy to ship one to you.

8. UNCOOKED, A.K.A. OHIO VALLEY STYLE // STEUBENVILLE, OHIO

While some bloggers have compared this practice to topping pizza with a Lunchables box, there’s no denying it’s an intriguing take on preparing a pie. Pizzerias in Steubenville are fond of cooking the dough and then adding uncooked cheese and toppings post-mortem, allowing the heat from the crust to slowly melt the cheese or using a takeout box to effectively steam-cook the top.

9. Kangaroo //Sydney, Australia

The adventurous meat lover may want to venture to Sydney, where local establishments like The Australian Hotel offer pies topped with rich kangaroo meat. Slices of 'roo tenders are marinated in a pepper and onion olive sauce. If that's too tame for you, the Hotel can also serve up a Salt Water Crocodile slice.

Google Assistant's New 'Interpreter' Mode Can Translate 27 Languages in Real Time

Move over, Google Translate. The Google Assistant's new Interpreter mode can translate spoken French, Spanish, and 25 other languages into English (and vice versa) in real time, according to Gizmodo. The new technology, which will eventually be rolled out to Google Assistant devices and third-party smart displays, brings us one step closer to having a universal translator capable of interpreting all the world's languages—a device previously only seen in sci-fi worlds like Star Trek and The Hitchhiker's Guide to the Galaxy.

Currently, the Interpreter mode is only being used at three hotels in New York, San Francisco, and Las Vegas. During a demo at Caesar's Palace in Las Vegas, a Google employee approached the concierge and asked questions in German. The concierge, equipped with a Google Home Hub, used a voice command to prompt the device to go into interpreter mode. From there, the two were able to carry on a conversation back and forth. Although one error was made, the translated text appeared on the smart display, which provided enough context clues to figure out what the intended message was, according to WIRED.

Technology reporter Shannon Liao at The Verge tested it out with Mandarin. She writes that although it's not perfect, it's still "a pretty big improvement from not being able to understand a foreign language." One common complaint is the lag—users must wait a couple seconds for the Interpreter to issue a translation.

However, Google's product manager, Vincent Lacey, told Mashable that the Interpreter mode is faster and more advanced than that of Google's Pixel Buds—ear buds that provide real-time translations, but only to the person wearing them. With the Interpreter, all parties to the conversation will be able to understand what's being said.

Following the pilot phase at the three hotels, the Interpreter will be available on all Google Home devices as well as third-party smart displays by the end of the month, a Google spokesperson tells Mental Floss. It will also be rolled out to third-party smart speakers and mobile phones in the near future, according to Google. Interpreter Mode supports the following languages: Arabic, Chinese (Mandarin), Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian, and Vietnamese.
