Likely scenario
AHole 1 cutts off AHole 2 forcing I whole 2 to swerve.
Ahole 2 looks up AHole 1 license plate to find is phone no.
Ahole 2 calls Ahole one screaming: "Hey-Ahole, you just cutt me off"
Ahole 1 responds: "eff You, you were driving slower than traffic"
Ahole 2 then swerves and passes and cutts off ahole 1
Ahole 1 and 2 either: a) cause a further accident or b) pull over to the side and beat the crap out of each other.
Seriously, these people didnt think the above scenario was more likely to happen than someone seeing their long lost friend in the carpool lane and dailing them to stop for a cup of jo at starbucks????
