See the road ahead: BMW’s curve-ahead view with eHorizon
summary
BMW builds a Curve‑Ahead View that detects dangerous bends from crawled map curvature and fleet speeds, matches and tracks them with Mapbox’s road object matcher/store and eHorizon observer, and renders only the relevant road surface in the HUD via runtime styling and an empty map style. It shows a 200 m display threshold, uses dynamic yellow/red severity indicators, supports offline operation with predictive caching, prototypes in 3 days to prototype, and once hit a testing crash when too many curves were tracked.
