Clarifications regarding “coasting” and twin roller dynamometers in 4WD operation.

Proposal by the expert from OICA to clarify concerns about terms "coasting"and “Twin roller dynamometers in 4WD operation”

Proposal identifies 2 concerns:
“Coasting“ – Coasting is defined in GTR 15 and UNR 154 and must be deactivated for testing, may raise concerns for the approval of many hybrid vehicles and for conventional vehicles with modern start stop systems.
“Single roller dynamometer in 4WD operation“ – This combination is forbidden by GTR 15 and UNR 154 for the Type 1
test. There appears to be no reason for this ban (restraint systems must meet requirements for all configurations) other than an assumption that the configuration is not used for type 1 testing
