People who suffer from road rage=morons. Scientific fact!
I was a shocker when I was younger. If anyone cut me up I used to chase them (all the way to their home if necessary) then scream expletives at the offender, who was usually too shocked to reply in any other way than to be really apologetic.
Thankfully I have seriously mellowed over the years and now I just let it go if anyone does anything silly on the road near me. I guess that may make me an ex-moron!
