The Personal Autobahn Effect

When traffic is not crawling at a snail’s pace, it’s generally racing along like a NASCAR speedway. Unfortunately, there is no lane, and the occasional slow driver is impeding the rest of us, Mario Andretti, on the road. Autobahn is the German word for a significant high-speed road restricted to motor vehicles capable of driving at least 60 km/h (37 mph) and having complete access control, similar to a motorway or freeway in English-speaking countries.

In most countries, it usually refers to the German autobahn specifically. The advisory speed limit of the German autobahn is 130 km/h (80 mph), but there is no general speed limit.

In my last article, I discussed one contributing factor to traffic in Washington, DC: Closing the Gap. Let’s now discuss another phenomenon known to exist around the Beltway and I-95: the Personal Autobahn Effect.

While it is common courtesy (and the law in some states) to yield to overtaking traffic, some aggressive drivers abuse this and treat the roads as their own autobahn.

When traffic is not crawling at a snail’s pace, it’s generally racing along like a NASCAR speedway. Unfortunately, there is no lane, and the occasional slow driver is impeding the rest of us, Mario Andretti, on the road. In this area, driving faster than the posted speed limit around the beltway and on I-95 is not uncommon. And if you’re on the left-most lane, you routinely see speeds exceeding the legal limit by 20-30 mph.

Each individual driver must decide what they are comfortable with. Still, some aggressive drivers take it further by insisting all drivers get out of their way to allow them to speed. Even if you’re doing 70 mph in the left lane and have visible traffic in front of you, these drivers will flash their lights, honk their horns, and give other visible signs to insist that you get out of their way.

What makes them so unique? If I’m doing 70 mph, keeping up with traffic, and dealing with the regular assortment of road hazards, what makes the guy behind me believe it’s his privilege – no, his right – to run up on my tail and try to intimidate me?

As I mentioned earlier, yes, it’s the law in some states to give way to overtaking traffic. But most of these laws also mention a second condition that must exist—a condition that most drivers ignore or simply don’t know—the overtaken vehicle must be driving abreast of another vehicle.

What does that mean? It means that if I’m driving in the left lane and AT THE SAME SPEED as the car is abreast of me, I must give way to an overtaking vehicle in the left lane.

However, what if there is no car next to me? Or, what if I’m safely passing in the left lane, to begin with? If an overtaking driver proceeds to harass you at this point, they are clearly in the wrong and only demonstrate the aggressive nature of driving in DC.

So, the next time you proceed to pass in the left lane, take a second to see what the traffic conditions are like ahead of you. Remember, we are all in this race together.
