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.

  • Please provide a link to the source. What have you looked up? Where? Does the Regulation contain a glossary?

    I’m voting to close this question because in its source material (not given) it is almost certainly a misprint. It would also seem to be involve a non-standard acronym. Commented Nov 2, 2020 at 11:46

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

enter image description here

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.

  • Not on-topic. rap is in-house. Commented Nov 2, 2020 at 11:48
  • Indeed. It's a sub-genre.

  • Is it helpful for a moderator to knowingly answer an off-topic question? Doesn't this severely undermine the credibility of ELU? How can one realistically help police the site? Commented Nov 2, 2020 at 12:42
  • @EdwinAshworth How do you know it's off-topic until wrap has been looked at? It may well have been a new meaning of wrap, akin to the jargon of all-over advertising. In this case, it isn't. Your comments are benefiting from hindsight.

  • Is it useful for a mod to give an answer (rather than a short helpful comment) explaining that 'wrap' should probably be the non-standard acronym 'rap'? Haven't you checked for a 'wrap' neologism? Commented Nov 2, 2020 at 12:59
