Buses? PAH. Begone with your filthy peasant-wagons


Re: toll lanes

The point of mass transit is to aggregate trips, where a trip is a vector with an origin (e.g. my domicile) and a destination (e.g. my workplace). In a perfect world where everyone lived in Megacity One and worked in Megacity Two, then all trips for all people would be vectors from Megacity One to Megacity Two, with vectors in the opposite sense at quitting time; and all trips could all be aggregated into one single Great Bus of Doom.

Or, if everyone telecommuted, the trips would be from your bed to your desk with a detour at the loo and/or fridge, then back again.

Reality is a perturbation of this of course, with more traditional cities substituting the city center for Megacity Two, and outskirts, suburbs, living areas, etc. for Megacity One.

It is in fact a more efficient use of resources like a road to group people who share the same trip on fewer, larger capacity transports. Fifty single occupancy vehicles on a road take up a great deal more space than a single bus with fifty passengers on it.

It is not necessarily a more efficient use of people's time however, particularly as you deviate from the Megacity model, e.g. you work and live in the outskirts, you live and work in different outskirts, etc. You are not aggregating identical trips anymore.

The Google car model is no panacea. Yes, you can get in your car and snooze. And if all things remained equal, great! But by definition they won't if everyone were to follow the same idea. A self driving car is not a teleporter. It will be on the same road as human driven cars (unless they're outlawed - good luck with that!) and will be as inefficient at aggregating trips. So expect a long commute anyway; you'll just be working, because the car will drive itself.

So, why not telecommute instead?
