    So, I guess you think that this new driver tracking would be cheaper than traditional obstructions (i.e. speed humps, chicanes, etc...)? I guess it could be, but what are the non obvious secondary and tertiary order costs of tracking all car movement? This seems worrying to me.

    A) 99% of traffic on every road drives above the speed limit. B) If speed is the issue, that's fine - address the speed. Increased traffic is not the issue in this case.

    Then the problem is “enforcing speed limits”.

  Roads are designed and constructed for a certain amount of throughout and vehicle type. The increase in through traffic means greater damages and more expenses.

    But how is this different to how the road system has developed from the start? People choose the popular routes by driving on them, then these are the roads that are repaired/upgraded. I don't know if it's cheaper per vehicle mile to drive on a large road or a small road, but I couldn't see it being very significant, but maybe it is?

      These roads are built to a lower standard. If they get more traffic, they will have to be maintained more frequently and/or improved. This is very expensive. Additionally, there is the safety aspect. It is more than just pedestrians at risk, there are other automobiles and structures to be concerned about. Tertiary streets, for example, probably won't have things like guardrails. Areas zones as residential should probably not have much through traffic. It is expensive and dangerous. The roads constructed to deal with that traffic are also built to withstand that higher load. Routing the traffic elsewhere will not significantly reduce the maintaining of said roads. Err... I modeled traffic. Hopefully that explains it. There's some good write-ups as complaints about Waze, if you want a keyword to find more info.

        Let's say that a given road has a certain service life, maybe measured in tonne-miles (e.g. a car which weighs 1.5 tonnes and travels a mile on the road would reduce the roads service life by 1.5 tonne-miles) (maybe not a good way to measure it because the damage caused to the road is probably non linear with increasing weight) What I don't know is if the cost of a small road per tonne-mile service life is any different from the cost of a large road per tonne-mile service life. If the cost difference is negligible then I don't see the problem. Maybe it is that different parts of the government fund the small roads than the large roads, and the parts of the government that funds the small roads doesn't have the budget to do much road work? Do heavy vehicles generally use these small streets, it seems like it wouldn't be worth it in a heavy vehicle with most small streets.
