Population: number of AI cars per generation. Higher explores more behaviors but runs slower.
Generation (s): time limit before evolving (or earlier if most cars crash). Longer gives cars more time to pass; shorter speeds up iterations.
Mutation: how much brains change when evolving. Higher explores more (noisier); lower refines (more stable).

Middle Save stores the current best brain for reuse on reload; Reset clears it to start fresh.
