Video from a GoPro Hero 3
Timing from Harry's Lap Timer (I switched to an iPhone since my last track day and didn't realize that my BT GPS and OBD sensors don't work for shit with Harry's Lap Timer on iOS, so GPS data is from the native 1Hz sensor)
Overlay from RaceRender which is lacking some bells and whistles that HLT has for overlays, but it's a lot easier manually syncing things on a desktop than on a phone
