I think this is only a few years old. 5 - 8 maybe?
A young couple on an American highway pull into a gas station. Somehow, this odd black spikey creature follows them or turns up there.
I think it's about the size of a tennis ball. It infects people at the gas station and they start sprouting black thorns and spikes, they lose control of their limbs and eventually their bodies and start attacking other people at the gas station.
It almost sounds like a comedy, but it definitely isn't.
