Motorcade
Every car. Same drive.
A shared live map for friends travelling in several cars: who leads, who fell behind, when to regroup.
Play with it, right here.
A working demo with sample data. Nothing here touches a real system.
Stretch the convoy
Drag any car along the route, or give the cars different speeds and press Drive. Motorcade watches the gaps and suggests where to regroup; turn-by-turn stays with the navigation app you already use.

Motorcade is a map-first companion for friends travelling in several cars. It answers what a convoy keeps asking: who is leading, who fell behind, did someone stop or lose signal, are we still heading to the same place, and when should we regroup.
It owns the group, not the navigation. Waze, Google Maps and Apple Maps keep doing turn-by-turn; Motorcade keeps the shared picture and sends you back to your navigator in one tap. Sharing is explicit, per drive, and ends on arrival.
Underneath there is a Kotlin API with shared rules for trip state and relative position, a SwiftUI and MapKit app, and an offline simulator that drives a whole convoy along a real route for previews and tests.
After the drive, a journal replays the trip with its stops, and a refuel log reads receipts on the device.
6 things it does well.
- Live convoy on one map, with route, speed and freshness
- Ahead, behind or alongside cues, only when confident
- Formation states: formed, stretching, regroup
- Opens Waze, Google Maps or Apple Maps in one tap
- Trip replay with stops and metrics
- Refuel log with on-device receipt scanning
