One of those zany German drivers was actually driving at the speed limit. This apparently angered a German truck driver who proceeded to beat the slower driver down.
Police in the western town of Bochum said the truck driver told them he felt provoked by the motorist "because he was actually driving 30 kph in a 30 kph area."
This'll be a great excuse for me to speed in the future. Never mind the fact that this was in Germany and we don't have an Autobahn...
