A gap is not a fact. It means we looked and found no source.

• No official page found for the toll amount for motorcycles at Mullayanagiri; the booking form shows it only after a slot is picked.
• Counts of hairpin bends on the Agumbe ghat differ: a newspaper says about 16, a trail guide seen only in search results says 14.
• No source found for forest check post timings at Agumbe (Someshwara) or on the Mullayanagiri road beyond the slot hours.
• No government order found for the Nagarahole gate hours or the two-wheeler restriction on the Kutta road; the second rests on a travel wiki alone.
• Nothing found for Sringeri or Madikeri: no rule specific to motorcycles, and no entry fee from an official page.
• The best months are sourced for Agumbe only, not for Coorg or Chikkamagaluru.
• No source found for the usual number of days riders take.
• Hairpin bend counts are added as header.hairpin_bends, which is not in the schema example.
• No video kept for the Agumbe ghat or Coorg; filming dates of the two videos are not known.
