    I’m not sure what point you’re trying to make and the metrics you’re using don’t really make sense. If one million people are driving with an average commute of 1 hour (personally I find it insane that that’s considered “normal” in some places, it should be an upper bound) and switch to a train which saves only 5 minutes each way they’d still save that same 10 minutes. Depending on what you mean by your “cars not driving” metric, that’s anywhere between 1 million cars (no more cars driving) and 255k cars (carbon emissions of 1m electric car commuters vs 1m national rail commuters, using this data).

    That’s not even accounting for the induced demand previously mentioned, making driving more appealing only creates more drivers which makes driving worse.

    And all of that is still only considering the traffic itself and not the effect of the infrastructure. Take a satellite shot of any random North American city and chances are a significant portion of it is just places to park a car. It’s a bit less common to see a city center dedicate half of its land to bike, bus, or train parking; that land is better used for people or business instead.

      The specific numbers dont matter.

      If you take 1 million cars with an average useage time of 1 hour a day and reduce that by 10 minutes thats roughly the same as taking 1 in 6 cars off the road from an emisions standpoint.

      Make it 500,000 cars and reduce it by only 5 minutes its roughly the same as 41,000 cars worth of emissions that werent pumped out of exhaust pipes.

      No it doesnt solve everything. Yes a well designed public transport system would be a much bigger environmental benefit. But its something that could be done with current tech and without massive infrastructure overhauls with a real tangible benefit for the environment and society.

        The numbers do matter because the numbers are literally your entire argument. You’re arguing building for cars is more effective, you cannot make arguments about effectiveness without numbers. Alternative transport methods can be done with current tech since alternative transport methods literally existed before cars. There are plenty of examples of places that aren’t car-centric, and most major car-centric cities weren’t originally built around cars. I honestly have no idea how you could have thought that’s a remotely reasonable argument? It’s utter nonsense.

        Even if your massive infrastructure overhaul argument was valid1, we’re literally talking about a hypothetical scenario where you can pump absurd amounts of money into a project.

        1. It’s not, just build other infrastructure instead of more roads. From a strictly capitalist perspective it pays for itself when more space can be used for taxable business instead of the dead weight of parking, and those businesses are more accessible to foot traffic making them more profitable and therefore generating more taxes. Not to mention the maintenance costs.
