Jerking time to full deceleration (after full wrap of ego vehicle and cut-in vehicle, road friction 1,0) It is from a new UNECE Regulation, no 157, about automated driving systems.
I found the document: it's a PDF and the phrase appears in the table on page 4.
Wrap appears to be a misprint. The previous page contains a diagram
which contains the phrases xx% Rap, 100% Rap and Release accelerator pedal.
The quoted phrase full wrap should presumably be full rap and means full release of the accelerator pedal.
