Er, people, not vehicles. From Mark Steyn's latest Happy Warrier column:

From London’s Daily Mail: “Scientists have created more than 150 human-animal hybrid embryos in British laboratories.”

You don’t say. Now why would they do that? Don’t worry, it’s all perfectly legit, the fruits of the 2008 Human Fertilisation Embryology Act. So some scientists have successfully fertilized animal eggs with human sperm, and others have created “cybrids,” using a human nucleus implanted into an animal cell, or “chimeras,” in which human cells are mixed with animal embryos.
Steyn launches from here onto a bit about demographics [sit down before the shock knocks you down! -ed] but somehow I think another point got missed.

British scientists are creating creatures that are part-human, part-beast. What, England doesn't have enough of them already?
