You’d be surprised by how widely applicable it is, it works for virtually any road. Small city roads, highways, even residential streets.
There also isn’t a maximum number of lanes for this effect (well, there technically is, but it’s too large to be feasible) because cars are an extremely inefficient way of transportation, so they take up a lot of space.
Roads also become increasingly more expensive with each extra lane added, to the point where it becomes economically impossible to keep adding lanes. You also need to demolish buildings if the road was already too close to them. And the cost of the extra lane isn’t a one off, it also generates a running cost for repairs and inspections.
That money is better spent on making viable alternatives to cars, which actually will help traffic or even fix it.
