Sure, I&#x27;m not making a value judgement, just stating how it is.<p>In my opinion, it makes a lot of sense to do that anyway, at least viewed from outer space.<p>Stepping away from &#x27;the economy&#x27;, London&#x27;s public transport system is used because it&#x27;s the only option. The roads are at capacity. I say this having driven basically every possible route in rush hour. They are full. I&#x27;m often surprised that we don&#x27;t literally end up having gridlock and just all getting stuck forever.<p>A metro system in my small northern hometown would be pointless because there&#x27;s hardly any road traffic so everyone just jumps in their car and has their nice personal space.<p>I find this quite interesting. Public transport has to be a better option for a critical mass to use it. This can happen either by it being much better (quicker), or by the alternatives simply ceasing to work.
