The Vatican has issued a "ten commandments" for drivers.
Cars can be "instruments of sin" when used inappropriately, but the Vatican suggests that prayer is a good use for the car -- and it's a good idea to recite the rosary while driving.
Seriously, they are behind -- haven't they ever heard of a MitzvahMobile? This is a thing that Chabad has been using for a long time.
It does speak to the idea that any modern technology can be used for both good and ill. Internet? Good for connecting people, but has obvious downsides. Telephones? Work for calling those in need, but can be disruptive. Ipods? Can shut you out of the world but can also bring in holy music or oral teachings....and I could go on and on.
I find it interesting that the Vatican is looking for ways to integrate their religious teachings into "modern" life -- and that they started with the CAR, something that's been around for so long.
