There’s Magic Earth which uses OSM map data but also integrates live traffic information. Not sure whether it works in India, though.

Have they tried/are there any plans of upstreaming that somehow? While I rely on proprietary services for car navigation today, if I move to a OSM-based services next, I'd want it to be similarly structured to actual OSM, not some proprietary bolted-on-top-of-OSM startup that will disappear/enshittificate within years.
