Getting alongside happens in two places: on long straights or in braking zones.
On straights, drivers use DRS (Drag Reduction System) — a rear wing that opens to reduce drag when you're within one second of the car ahead. It's like removing a parachute from your back.
In braking zones, it's about timing. Brake later than the car ahead, and you might sweep around the outside. Or divebomb — brake super late and dive down the inside, hoping to complete the move before the next corner.
