11. The expert from OICA proposed amendments to Regulation No. 51 with the aim to ensure transparency during the type approval process in situations where the manufacturer could either use mechanical or electronic devices to control the gear shift, or take measures to avoid accelerations greater than 2.0 m/s² (ECE/TRANS/WP.29/GRB/2018/2 and GRB-67-17).
