There are 2 situations where I love to play with the paddle shifters in town driving. First you have to place both hands on the steering wheel and fingers resting on both paddle shifters, always ready to trigger. Do not use the paddle shifters if you are approaching a bend where you need to cross both arms.

First scenario is for slowing down the car speed.
When you are approaching a cross junction traffic lights and you are taking the left turn that does not need to wait for traffic lights and the bend is less than 70 degrees, you just left tap three  or four times to bring the gear to 3rd and use the engine pull to slow down the car while both hands on the steering wheel guide the car exit the bend then step on the gas and right tap every 1-2 seconds to zoom away. The objective is to use paddle shifters to slow the car speed to 40kmh or less for beginners to get a good feel of the engine braking effectiveness and make use of that experience for further exploration.

The second scenario is for overtaking.
If it is a double lane and you are on the left lane tailing a car at 60kmh. You would normally swerve to right lane and apply more pressure on the gas pedal. If you want to pull away from him for300 metres, you would usually step hard on the gas pedal by flooring it suddenly. But with paddle shifters, you just swerve right, apply more pressure on the gas, then left tap 2 to 3 times to put your rpm into 2500rpm region and shoot straight, every 1.5 seconds right tap. Do not lift up the gas pedal. Maintain same position where you are flooring the pedal at around 90% down. Otherwise the car won't launch forward. Don't have to see the rpm or gear selection. Just concentrate on road ahead. You will notice your speed is 100kmh when you decide to slow down. Don't do this in residential area.

I am not a racer. First time play paddle shifters. I find it a thrill at the moment but I am sure the novelty will fade off as time goes by. But for now let's have fun and enjoy the good pick up of the Preve.
