It's only a constant factor improvement, but it is a massive constant factor improvement. Mass transit easily scales up to the limits of our building construction abilities. You can only make buildings so tall before you start getting diminishing returns on density because you need to have more and more space taken up with elevators, HVAC, plumbing, etc.
Even in an incredibly dense city like Paris, they aren't running out of space to put subway lines. They are limited by by the number of people who need to get places and by the cost of building more subway lines.
- barrkel 9y agoWhy do you think there are so many scooters and motorcycles in Paris then?
- TheCoelacanth 9y agoNot sure what your point is... Paris doesn't have enough subway lines to handle all transportation needs for everyone, but that's not because they ran out of space to put the subway lines in. It's likely because they have covered enough people's transportation needs that it wouldn't be cost effective to put in more lines.
