Seems like "billion-vehicle-miles traveled" is not a good metric; people travel faster in aircraft and in cars than they do on bicycles and on foot. Time spent travelling should be a better metric.
- InitialLastName 8y agoTime spent traveling isn't necessarily better; by some metrics people going faster are just traveling more effectively. It's a question of whether we rate the travelage by utility or by luxury. If we consider it for utility, vehicle-miles travelled is a perfect metric. If for enjoyment, time spent traveling is better (but still not perfect).
- scatters 8y agoUtility doesn't scale (linearly) with distance. Consider someone walking 0.5 miles to a neighborhood store versus driving 5 miles to a big-box store. The big-box store may have a larger selection of product lines and slightly lower prices, but there's certainly not 10x the utility there.
