 The scheme has attracted criticism from motoring organisations such as the AA, who in 2018 reported that many members were concerned that speed limits were being imposed without good cause in situations where traffic was light.In response, Highways England stated that they had "started a comprehensive review of how variable speed limits are set, including the amount of time they are visible to drivers".In January 2020, it was announced that a review was planned after freedom of information requests showed that near misses had increased up to 20-fold, and that 38 people had died.
