The "car tax" name isn't much better, not least because motorbikes and lorries pay it too, and a good number of cars don't. "Road tax" is the better name in that sense; it's just many people get exempted to some degree. Based on carbon emissions, which is the main escalator, if bikes were included they would be fully exempt from the tax. Maybe cyclists (and other exempt users) should be allowed to get a special green disc for free to show they're part of the system and to shut these luddites up.
