memorize maps and bus routes in advance (no phone)
if leaving on foot, pass through areas with no cameras such as wilderness or spillways but which you can explain your presence (eg, looking for a lost pet)
don’t brag about shit to anyone
oh yeah, memorize phone numbers for a lawyer and or close friend who you can call if you’re picked up on suspicion and detained.
Small note: There are other ways to identify you such as telephone data, DNA, fingerprints, clothing etc so also think about those
if i was make a video game or fictional novel about this sort of thing, I’d also add:
