The single-engine taxi restriction from EWR Taxiway RG began around [Date] and I have observed minimal awareness and compliance since then. I believe a significant contributing factor to this un-intentional non-compliance is that the caution is located on the EWR  10-9D at the bottom in plain text. The ORD 10-7 for the same caution is significantly more visible immediately after the Safety Alert boxes and is in bold type.
Captain reported violating the single engine taxi restriction due to the inconspicuous location of cautionary note as well as the plain text instead of bold type.
