so police can trace me if i was to go to a hotel ... i mean does it take time for police to do that , like dont they need an authorisation or smth ?
If you are required to use a cc, yes. And the way things work nowadays, they can catch where you're at as soon as you swipe that card.
If you find a hotel that doesn't require a cc, and only id, you might be ok. Because unless you vandalize the room and leave, they won't call the police, and the police can't locate you. The most the hotel does with your id is make a photo copy of it. That's it.
i wouldnt bring my phone , i would use cash .. is there anything else i should be careful of? like could i use a train to go far? should i be careful not to walk in streets with cameras or am i too paranoid x.x
Nearly every place you go has a camera. Even though you can't see them, there is a camera somewhere looking at you while you're walking down the street.
Trains, planes, subway, buses, they all have them.
The only vehicle I can think of that you would probably be safe on, is a freight train.
