Therefore 3 Points for ESC are deleted from : Points related to LKA and LDW performance increase from 1 to 3. This may include an incentive for availability of blind spot systems. 2018: SBR will keep 3 points associated. Of these points, 2 points will be for rear seat SBR including ½ point for advanced occupant sensing systems. 2018: Points allocated to the assessment of advanced Lane Support Systems increase from 3 to 4. AEB Interurban updates will not aim at addressing significantly different crash scenarios (e.g. no braking in head-on scenarios) so the points remain the same. 2020: SA total points increase from 13 to 16 points with the extension of AEB Interurban and inclusion of Junction Assist. 58SA
