CDN and cybersecurity giant Cloudflare held its Q2 earnings call on Thursday, during which chief financial officer Thomas Seifert gave a concerning prediction about what the web...
I had a realization recently that with driverless cars becoming more common that one day I’m going to be stuck in traffic surrounded by dozens of other cars that are completely empty. They’ll just be going to pick up a human driver somewhere or going to park and no one will care because instead of eliminating traffic we’ll just ensure humans are entertained while stuck in it.
Why bother to fix traffic congestion if you can just play PlayStation the whole time or whatever?
If most cars are autonomous, and capable of coordinating with each other (via mesh network, for example), then traffic congestion might become much easier to prevent reduce and solve mitigate. (Edit: Based on responses, I may have chosen my words poorly)
You’re probably not wrong though. I imagine it’ll get worse before it gets better.
Ha ha. Traffic will move to let billionaires through quickly.
Regular folks will be stuck in endless traffic trapped in driverless cars that charge them $5 a minute for the privilege all while playing the same loud and obnoxious audio video ads on repeat for hours on end.
I don’t believe we will ever get coordinated autonomous vehicles. You will never be able to absolutely trust the information you are getting, whether it’s because wireless sucks, auto manufacturers couldn’t agree to or properly implement a universal standard, software bugs, or malicious behavior. If we want it to be safe, then the cars will have to drive cautiously and be prepared for behavior that was not properly communicated. This will not be a form of driving that is fundamentally different to what we have now.
And even if you could implement perfect coordination between autonomous vehicles, how would you be able to take advantage of it in the real world? Ban all human drivers? What about pedestrians and bikes? You still need crossings and traffic lights for an area to be livable by humans. You still need to drive slowly next to a pavement where someone could eg trip and fall onto the road.
Traffic congestion will always be a thing. The real world is too unpredictable. You can’t pack a highway full of cars and expect them to drive highway speeds. One animal jumping on the road and you’ll have a massive accident because nobody can avoid anyone
Traffic congestion doesn’t happen because of lack of coordination. Coordination prevents collisions. Our success rate could be a lot better but the system does pretty well with coordination limited to blinking lights, a noise that says “fuck off”, the mutual knowledge that we all got the same training and the private knowledge that everyone else on the road is a suicidal idiot who slept through the training.
Congestion is a physical property of the road network. There’s a physical limit to the number of cars you can push through a road in a given time period. Drive the cars too fast and they fly off the road when it bends, or cars slam into each other when a deer tries to commit suicide.
Traffic is well modeled as an incompressible slightly non-newtownian fluid, like runny oobleck. If you apply more pressure/increase vehicle volume the fluid starts to bind up as it becomes harder for the cars to maneuver without collision, regardless of coordination.
You reduce traffic by taking cars off the road, or scheduling utilization. Self driving cars won’t help, and we can do both of those without them. Long term they’re likely to make collisions worse because humans don’t know what they’re going to do, so the primary mode we have of coordination, “the theory of mind” will break down. Right now they’re so uncommon that you assume any car is a human who reacts and prioritizes like you.
Tear down the freeways and replace them with trains.
In other words - car usage expands to the limit because human nature is to use the resource until it gets inconvenient. The gas expands to fill the container.
I won’t disagree with what you said, but I’ll disagree that it’s the same point I was making.
My point was that there isn’t a technical solution to traffic congestion. You need less fluid or a bigger pipe. What you correctly mention is why a bigger pipe won’t work for humans when it does for water.
And out of pure pedantry, I’d disagree purely because my analogy said “non-newtownian liquid” - those don’t expand. :P it’s more like a hyperactive toddler manically jamming silly putty into a PVC pipe.
Definitely a possibility but i would push against the likelihood of it – it could also solve a lot of our traffic issues because humans get emotional and cause traffic jams by doing easily avoidable things like clogging up the left lane with a train of tailgating cars, etc.

One day when you’re stuck in traffic, it will be all horsecarts. Which are also capable of bringing a drunk driver home.
