a better idea: DON'T PROX MINE VEHICLES!I had a hotwire plant her load of c4 on my new orca before I could get to it. I asked why, and the reply was "It helps". I, having nothing I could do about it, took my booby trapped orca...and promptly fell out of the sky when an apache buzzed by. Ok, it helps kill you faster. The hotwire probably assumed that I was going to attack, and wanted to bum some points off me. She did that all right, and got PERMANENTLY stuck on the 'ol hate list.
Unless the driver specifically invites you to mine them , DON'T. If they don't SAY they want you to, then it generally means that they DON'T feel like going kerplooie.
On the flip side, if there's no one around and I'm swapping vehicles(a hummer for a med tank), I will lay the remotes on the hummer so no enemies use it to run away. If it's your own credits, feel free to destroy it, but if it is someone else's tank, they get VERY p!ssed when they see it looking like a big proximity porcupine.
