Certain ideas were left out of a COE review, including priority for families with children and a new ride-share car category. The Land Transport Authority, or LTA, cited difficulties in implementing these ideas fairly as the reason.

Further details about the review and the rejected ideas are available from the source. The LTA's decision not to include these proposals suggests that fairness in implementation was a key consideration.

The source provides more information on the COE review and the ideas that were not included.
