Hi Ayumu "Osaka" Kasuga,
It has been great to see you contribute at such great capacity across India, however there are some observations that we have come across regarding your edits especially regarding motorways. As per OSM India highway classification   
motorways are defined as Completely access controlled tolled highways designed for high speed road travel 
attaching the document you may refer to classify these roads better

would be glad to connect to discuss further
