This graphic does not need pedestrians or bikes. They aren't competitive with vehicles of any kind when you start talking about multimile distances.

A more realistic simulation would be including the loading time for each vehicle type (car/bus/train) for a 5, 10, and 20 mile distance. That way you see how these vehicles are actually used rather than a shitty first past the post "race". Removing the loading/unloading times of each vehicle wildly skews it in mass transport's favor.

It would also be interesting to include usage costs associated with each mile range. I figure a bus pass for a 20 mile trip is a lot cheaper than loan payments, gas, and maintenance for a single passenger car ride.

Things really improved when urban planners were forced to design cities as one long road with a single stop at both ends, and every commuter were forced to start their journeys from a single location at a specific set time.

A more interesting model would be starting and ending in random locations across a wide area, starting at random times.

That's the kind of visual we need to make the point. But I wonder if these analyses account for the fact that buses/trams stop for passengers and cars/bikes go "straight" to the destination?
