Even the Pope is getting tired of the way people are driving. He came out a few months ago on the 10 commandments on being a driver:
The Ten Commandments for road use are as follows:
1. You shall not kill.
2. The road shall be for you a means of communion between people and not of mortal harm.
3. Courtesy, uprightness and prudence will help you deal with unforeseen events.
4. Be charitable and help your neighbor in need, especially victims of accidents.
5. Cars shall not be for you an expression of power and domination, and an occasion of sin.
6. Charitably convince the young and not-so-young not to drive when they are not in a fit condition to do so.
7. Support the families of accident victims.
8. Bring guilty motorists and their victims together, at the appropriate time, so that they can undergo the liberating experience of forgiveness.
9. On the road, protect the more vulnerable party.
10. Feel responsible towards others.
Nothing about Thou shall use turn signals more often though. But that would fall under #3.
