# Tarmac

> Group navigation for supercar drivers and motorcycle riders. Plan the route once, drive it together — nothing changes unless you confirm it. Tarmac is a UK-first group navigation app for iPhone and Android (early access via hello@tarmac.app).

Key facts:
- Nothing changes the route unless the rider confirms it. There is no automatic rerouting.
- Traffic can suggest a diversion; diversions are temporary overlays that always rejoin the planned route. The saved route is never overwritten.
- Group roles: organiser (create, invite, edit route before start), lead (start and pause), rider (follow and share location), sweep (see who is behind).
- Each rider confirms their own diversion unless the group policy is organiser-only.
- Routes use Stop, Via and Shaping points. Google Maps links can be imported; routes can be exported to Google Maps as honest legs (for example "Leg 2 of 5").
- Location is shared only with the group, only during an active ride.
- Safety camera alerts and CarPlay are not available at launch.
