If I were to say “at 3am, almost all grocery stores are empty, yet almost all houses are occupied, so look how much land is being wasted by grocery stores” would that be fair and representative, or picking and choosing a time to suit what I’m trying to say?

Even if we do pick and choose in favour of cars, the train is still probably more space efficient even with only around 30-50 people on board so why put yourself in a position where you can be rightfully called out as misrepresentating the data?

For the last part, have you been to London? Outside of 7:30-9:30 and 16:30-20:00 you’re pretty much guaranteed a seat anywhere on the network - when you consider that 27% of the capacity of a piccadilly line train is seating, I would call a train that’s 10-25% full near empty in the same way that a car with 1 person in would be near empty… And if you look at the streets of London during the day, it’s all taxis and vans, generally the taxis are a mix of families and people alone, leaning towards families as it makes more sense financially to get one the more of you there are, and the vans generally have groups of people who are using them for work
