It's always "It's a bluesuit, GET HIM!", and that's how the driving works, the agile driver enters the map in realtime, draws the whole attention of centaurs/floaters on him and sets the radio signal for his leveling teammates. He then proceeds to run around in circles, while his teammates enter the map and pepper the tunnel-sighted critters with bullets, but even if as Pistacja pointed out, if one could draw attention of a rogue centaur, he leaves the map then and enters it again, while the centaur runs back after the Driver.
So, while i call this teamwork rather than exploit, it's still illogical... There's a scripting-intensive possibility of NPCs estimating the danger radiating from their foes.
That means, a thug engaded in combat with NCR, encountering a lvl1 bluesuit, will set higher priority on major threat, dismissing the noob. Also, players armed with only their Unarmed skill or
this would get a advantage in PvE - their enemy wouldn't expect what hit them.
If you continue this thought, you could also implement FEAR, so your average Raider Joe would rethink attacking a bunch of guys in CAs with Miniguns, running for his dear life instead, especially if he's low on HP. (Yay, ego increase!
That would be a refreshing and logical, or you can just imagine all of them being on drugs or plain primitive-brained.
