The expert from Germany introduced ECE/TRANS/WP.29/GRSG/2019/27 on possibility for a temporary modified view and based on GRSG-117-40 highlighted the difference between the relevant field of view and the required field of view. The expert from France, in principle, welcomed the proposal however raised questions on conditions for activation or de-activation of temporary modified view by the driver and requested a better definition of ‘temporary manoeuvre’. The expert from the United Kingdom engaged in the discussion by supporting concerns raised by his French colleague and adding that the modified view could end up with new blind spot areas.
