I think your right, there are too many people on the road who generally don't give a xxxx.
There are also some people with children in the car who don't think either. I once had a woman with kids in the car trying to chase me because she pulled out whilst I was along side her, so I dually tooted, and can only assume woke her kids up.
Are you sure it wasn't your wife? LOL
I would like to see you try to get Tom and Harry in child seats (both now over 6')
