00:00:00 intro
00:00:30 navigate on openpilot
00:01:46 how it works
00:02:00 OpenStreetMap, overpass, valhalla, mapbox GL
00:02:20 how it works: the map
00:02:55 mapbox GL
00:03:15 maps to draw
00:04:12 how it works: the route
00:05:05 map matching
00:05:45 valhalla to snap to OSM graph
00:06:05 how it works: the model
00:06:15 need to squish down the maps
00:06:38 compressing the camera videos with neural network
00:07:40 how it works: the model autoencoder
00:07:55 encoder and decoder
00:08:55 reconstructed map
00:10:02 it works pretty well
00:11:05 deploying to comma three x
00:11:15 mapsd, navmodeld, modeld
00:12:20 taco bell video
00:12:44 the devil is in details
00:13:02 map scale isn't constant
