Not wrong. When doing it the first few times they need the cushion of extra gas (lug avoidance) until they get the clutch thing. When they get the clutch thing a funny thing happens - they ease off on the gas. If a very slow moving car is at the lug point, its either going to die anyway OR its going to lug-lug-lug-lug until the who-knows-how-much-gas-pedal-they-gave-it catches. Then it takes off like green light at a drag strip and everyone starts screaming.
