Road heights
Speeds in km/h. Attack speed is taken where the car crosses the attack line. Average speed and angle run from the attack line to the finish line. Zones count when any corner of the car enters them.

Pick a layer, then tap the map to add points to a line, zone or clip, or drag one to move it: each point takes the road's height where it lands. The track limits can't be changed here, only a stray point erased. Drag empty space to pan. Lines use two points: one at each end, like the cones.
