another way to think about it:
πr^2:
3.14 * 100^2 = 31400 mi^2 (5M+ people)
nealry 2X Netherlands (16000 mi^2): 17M ppl
southeast of England, excluding London (1200 mi^2): 8.5M ppl
England as a entire country (50000 mi^2), which is 1.5X your "Austin" area: 54M ppl (slightly bigger than the "Austin" area with 10X the people)
I can't really consider Austin urbanised in any proper way, which is possibly why a bike trailer works.
