if you want to use a vehicle as an analogy then don't use a car... I'd use the railways as an example because you can quite possibly jump on and take it for miles! It costs the locomotion industry nothing for you to hop on a empty car and ride for free as with the internet user... their access is unlimited for what they pay you're costing them nothing extra. its just a matter of principle, a dumb principle.

Now if you were always connected to the guy's wifi then I would see how there could be an issue because you'd be taking a great deal of his bandwidth and he'd probably notice your presence. I'm not talking about sitting on someone's connection hording files night and day via bittorrent lol

You tell me who it hurts and why it hurts them and maybe i can start to see things your way.
