Papal teaching
While it’s nice to see the pope is getting a more energy efficient set of wheels, a Mercedes hybrid engine Popemobile for tooling around the Vatican, maybe some older versions would have worked just as well.
I suppose if energy savings alone was the issue, he could have opted for something like the vehicle used for John Paul II’s visit to Mexico in 1999, if the Pope didn’t mind standing in line with the College of Cardinals at the bus stop in the mornings.
Or, if he’s got to travel around on his own, he could use the gas-miserly Piaggio Popemobile:
But, apparently gas consumption isn’t the prime consideration when it comes to designing a Popemobile: the new vehicle may be greener, but it’s still just an armored truck with a bomb-proof camper shell. A pretty basic idea, and a good one. I suppose there’s something to be said for imitation being the highest form of flattery, but when the design inspires a Ciudad Camargo mechanic and his client is the Gulf Cartel (though he overlooked the energy efficiency) maybe someone should have reminded them that “Thou shalt not steal… or steel plate”:
