The most deceptive intersection in the world

 

There may be other turns that provide a driver with misleading visuals.

Could be.

Quite likely, in fact, considering math and statistics and so on and so forth. There are many places to be encountered on our travels and in our daily routines.

But I’ve never encountered one quite like this.

Heading home, there is a turn that needs to be made. As you approach it, if there is a car coming in the opposite direction, it always feels as if you need to stop because there is no way you’ll have enough time to turn left and clear the road in time. And yet, in all of my experiences to date, there always is time to turn.

Plenty of time in fact.

Enough time to come to a stop, adjust the radio station, decide you don’t like the new station and adjust it again, realize you don’t like that station either and open Spotify, search a bit and find something you haven’t heard in quite some time, realize how much you like the song that you’ve chosen and consider for a bit why you don’t play that entire album more often, send a message to your partner with a link to the song, wonder whatever happened to the band and look them up online, find out they’re still performing and are currently on tour, order tickets for a concert coming up nearby, make dinner and hotel reservations on show night so you and your partner can have a nice night away, look up and realize you never needed to stop and that you still have time to turn onto the side street before that approaching car arrives.

That much plenty of time.

First time I found myself at the intersection with traffic coming my way, I slid into the lane for turning, came to a complete stop, and began to wonder if it was me.

(Writer’s note: Drive safely. Obey local traffic laws. My saying that at this intersection—this unidentified intersection—has plenty of time for you to make the turn is in no way intended to be even a whiff of a suggestion to not stop. That safety tip in place, back to wondering if it was me.)

What the heck was going on? Because I finished that stop and, based on a really old joke but it works, could have timed the approaching vehicle with a calendar instead of a watch.

Now a regular in the neighborhood with dozens upon dozens of left-hand turns to my credit, I’ve decided it must be some kind of physics defying optically illusionary natural rarity.

Overall, the location is somewhat unremarkable. Don’t get me wrong, it’s plenty unique, somewhat picturesque, and a lovely example of local beauty. But it’s also borderline anywhere and everywhere your town.

To begin with, it’s a one lane two lane road. By that, I mean that it is an opposite directions two lane road, where this one has a median that’s about six-feet wide running between the lanes. Not a boulevard, kind of remote for a parkway, but boulevard and parkway probably work better at summing it up than other options would. The parkway’s median breaks, as stripes and curbs and medians do, when an intersection shows up. And at those points, the set up of the median is such that it thins to create spots to safely tuck you and your vehicle in, get out of the flow of traffic you were a part of while you wait for the opposing flow of traffic to allow safe passage for your turn to a new road.

Next for your consideration is that the road has, depending on your direction of travel, a very slight lift or a very slight drop to it. In the case of our x marks the spot of deception, you are a bit above and looking downhill at the oncoming cars. Cannot stress enough how slightly elevated a vantagepoint it is, but, it is.

Then there’s the speed. While it is a fairly major road, the speed limit reflects that it is also heavily residential. Varies, for the majority of its run, between 30 and 35 miles-per-hour.

My guess is that factors such as these—trees and brush in the median creating a mildly obstructed view, change of elevation altering sightlines, lower speeds without routine traffic-based landmarks—along with others combine to create something of a perception anomaly.

Summary? None of it is exactly what you’re used to seeing from a presentation you’re used to having.

Have you ever heard of a gravity hill? It’s a location where down appears to be up, so to speak. The road and landscape, from design to set up to more, means you could come to a stop, believe you are looking uphill, shift into neutral and release the brake to find your car begin to roll forward. You’re going downhill, but every sensation says you are moving uphill.

Most studies into gravity hill locations seem to indicate that the most significant factor seems to be the horizon. Or, more specifically, that the view of the horizon is blocked in some fashion, removing a significant visual cue that we normally take for granted.

I have no idea if what I’ve stumbled upon is some gravity intersection of some sort. Never before considered that I can’t see the horizon that well at that spot. And to be fair, the name gravity intersection would need a bit of consideration, since you aren’t rolling uphill. But there is something going on here. Something a bit different and unusual.

Until I sort it out (and definitely after I do as well), I’m going to come to a complete stop before I turn. Just seems like the wise thing to do when nothing feels right about everything being right.
