Muggings rarely cross anyone's mind, except maybe when carrying an exceptionally large sum for e.g. buying a used car (which i the biggest transaction customarily done in cash, by a wide margin). Concerns about muggings are usually consolidated with the more general though of "what if I somehow lost my wallet" and that is dominated by concerns about the credit, debit, ATM and ID cards that also reside there (yes, credit cards are not terribly rate, but many are rarely used in face to face transactions). Losing a few days worth of cash transactions isn't high on the list of annoyances that would come with a lost wallet.
By the way, the big costs of daily life, like rent, insurance and the like are not settled using credit cards, cheques or cash, this stuff is all done by bank transfer and has been done by bank transfer since long before credit cards became somewhat established (for occasional use).
