Overtake Rush

Floor it down a sunny divided highway packed with traffic. Steer through gaps, brake for walls of trucks, and skim past cars for close-overtake bonuses — the closer, the richer. Bank cash from every run, then climb the 9-car garage from the rusty Mule Pickup to the 230 km/h Apex Hyper. Four biomes roll by: savanna, suburbs, seaside causeway and canyon. How long can you keep the rush alive?
