### Chicane

A sequence of tight, alternating turns (usually an S-shape) designed to slow cars down, often placed before a fast section of track. Chicanes are sometimes added for safety reasons to reduce speeds at dangerous parts of a circuit.

### Apex

The innermost point of a corner on a racing line. Hitting the apex allows a driver to carry the maximum speed through a turn. A late apex delays the turn-in point to prioritize exit speed, while an early apex favors entry speed.

### Racing Line

The optimal path around a circuit that allows a driver to carry the maximum speed. The racing line typically involves using the full width of the track, entering wide, hitting the apex, and exiting wide. It may differ from the geometric shortest path.
