Spanker, what you're doing is actually creating MORE wear and tear on an automatic transmission.
Autoboxes are meant to be taken out of Park, put into reverse to back out of the driveway, then put in Drive and LEFT THERE until you are at your destination, where you will again put it back in Park and exit the vehicle.
Changing the shifter position for every red light from Drive to Neutral releases all the clutch packs in the transmission. Dropping it back in Drive and planting the go pedal when the light turns green slams everything back into place and creates excessive wear. Leaving the transmission in Drive and holding the car with the foot brake is the recommended and proscribed way to wait for a light. If someone behind you is dazzled by your brake lights, as said before, they can look away.
Over here if you release your foot brake (thereby extinguishing your brake lights), the person behind you will most likely assume you are moving forward to take off. Because whether it's an auto or a stick, we hold the car with all four tyres (the foot brake) instead of trying to hold it with the two weakest brakes on the car (the rears on a FWD). If you hold a car on flat ground with the hand brake on your driving test over here, it's a failure item for the previously mentioned reason. If you're holding with just the parking brake and someone slams into the back of you, you've got the two weakest brakes and the two tyres with the least amount of weight on them to stop you from being shoved either into the back of the car in front of you, or into the intersection if you happen to be the first in line.
Also if you're the only one at an intersection and you don't have your brake lights lit and someone rear ends you, over here you
can be found at fault for not properly indicating that you were stopped!! Doesn't happen too often, but it can. Normally it's the person that rear ends' fault.......
Now someone will come along and start in with the newer design of "Triptronic" and auto/manual transmissions that are an entirely different animal......
