In reply to two_tapirs:
This is from the access notes on the cheyne weares crag page:
Dungecroft Quarry (and the Road Rage Wall) - From the main Cheyne Weares car park walk south (right - looking out) from the car park along a track down into a large disused quarry. The Dungecroft routes are along the quarried wall to the right. The abseil point for the Road Rage Wall is a staple situated on a large boulder on the cliff-top, in front of a pile of waste stone. About 30m north of this is a short block wall set back from the cliff edge where abseil bolts for the Bariatric Buttress can be found.
I never knew you could ab down to road rage...
