In the US intent has a lot to do with it. For example, if you're driving your work truck around from job site to job site it's normal to have a bunch of tools with you. However, if get pulled over because you caused a cops "antenna to go up" and you have a crow bar, bolt cutters and duct tape in your trunk you may be charged with possession of burglary tools. It depends on the context and circumstances.
Of course the tricky part of being equipped to survive is many of us carry all those things in our vehicles

I have things like duct tape, rope, etc. Would probably look like a kidnapper or something. I try to carry pictures of each camping trip showing some of that gear in use to help show innocence.
And not just the police but $big insurance company$ who said you don't need all those things in your vehicle so we refuse to cover them and if you fight us we'll just say if your carrying all that stuff just to drive to work then you must be using it for work so we don't cover it in that case anyway. Needless to say I'll never get insurance through Allstate again.
