Motorcycle navigation that loves curves

YouTube

A motorcycle sat-nav of mine, for me: it favours twisty back roads, announces turns 'by ear' and records rides with curve statistics – including share-ready images.

Exactly how I picture motorcycle navigation: not the fastest route, but the most fun one. I dug deep into the Valhalla routing engine and taught it to reward curves. It's also my first strictly spec- and test-driven project – a vibe-coding experiment with Claude Code.

What I learned

Understanding a routing engine from the inside and building a project rigorously spec- and test-driven with AI assistance.
