A minimalistic directions service aimed at users of feature phones/dumb phones, terminal-based browsers, low-bandwidth connections, screen readers etc. Best suited for public transport directions. No JavaScript requirements.
As someone who is currently enamored with Meshtastic devices, several of which have built in GPS, this is making me wonder of future iterations of the software and being able to somehow utilize the directions on the mesh.
