UPS non gira (quasi) mai a sinistra

I camion e i furgoni del corriere UPS tendono, nei paesi con la guida a destra, a seguire percorsi che portano a girare in senso orario per risparmiare carburante e stress.

UPS engineers found that left-hand turns were a major drag on efficiency. Turning against traffic resulted in long waits in left-hand turn lanes that wasted time and fuel, and it also led to a disproportionate number of accidents. By mapping out routes that involved "a series of right-hand loops," UPS improved profits and safety while touting their catchy, environmentally friendly policy.
