I worry that if I were mugged in the street it would be very easy for
the mugger to access the phone simply by pressing my finger against

Finger print sensor but yes that's how it works, they would have to
use one of the fingers the device knows about though. A good guess
would be the 1st or maybe index finger on either hand.

They would then have to make sure the device couldn't go back into
lock mode, unless they took your finger with them...

And with the best systems, it has to be a live finger.

My Android takes quite a few scan attempts (more than I'd like)
before getting stroppy and wanting another form of authentification.
It'll also ask for that "out of the blue" as well.

Trivial to use a better system which doesn't.
