As with other traffic interventions, there's a risk that Google's approach to spreading traffic could backfire. This concept, known as "induced demand," also applies to efforts like adding a lane to a critical highway, which temporarily relieves congestion, until traffic rises again. "You can do this, but you cannot be too successful, because if you are too successful, then more people will start driving, and essentially you'll be back to ground zeroâ¦"
Oh fuck all the way off.
This idea of "induced demand" always comes up in the context of traffic improvements, as though the goal of traffic design is to keep people from driving. (We had a sale on apples, and everyone bought our apples! Damn this counterintuitive induced demand!) Add a bypass and now it's full of cars? Good! That was the whole point: to help people live where they want to live and get to where they want to get to. Every car making up that new traffic jam is being driven by someone who is, on balance, willing to sit through it because of the positive effects it's had on them.
You can point to pollution and carbon emissions and freeways splitting communities, of course. There are plenty of reasons not to want more roads, and plenty of reasons to want to force people to adopt different living habits than they want to. But if that's your aim, at least be honest about it.
