Currently I just default the view to Sydney but this could be modified to view where a user is (rough IP geolocation), and I've got a work in progress PR for storing the lat/lon/zoom in the URL so you can bookmark/share locations.
I imagine there's a few trick things that could be done on the map page like nailing the coordinates, doing the timer --- and then bouncing over to Google Forms via the power of pre-filled links.
The Google Form makes it very easy to bootstrap collecting emails (reliably) to prevent any spam that may be submitted, but it's long and confusing to new users (already got that feedback).
Ideally in future you could click on an intersection on the map, use a timer in the page (could optimise the UX), associate an email address with a one time code (on first load/if no cookie) then submit (with the OSM node ID already filled in so I don't have to manually update that).
So that would be the long term roadmap - if it gets enough traction and I have time!
