Have these priests never been behind the wheel of a Hummer?
Commandment No. 2: The road shall be for you a means of communion between people and not of mortal harm.
Have they never been stuck behind a roving PennDot crew on the Schuylkill Expressway? A spiritual experience, it is not.

The guidelines are meant to remind drivers about the "phenomenon of human mobility" and "moral aspects of driving."

"Being human means coexisting with each other and roads should therefore be more human," she told me after reading the report.
