Longrider points to a government report (not that that is anything to go by) that suggests that the car (assuming you buy into the whole global warming argument) is frequently a greener option than rail.
This is an idea we are not entirely unfamiliar with here at Transport Blog.
I commented that the report did not seem to mention occupancy rates. As I have mentioned before these have a big impact on a train’s overall score.
Hey, hey TGV; was it you who caused the rising sea?
