* When on plane/flat road or sloping down I put the lever on neutral, as the car will keep going at the same speed or faster (coasting) without using petrol.
* I use that also when expecting to stop for a traffic light, few 100 metres ahead.
* I believe it also to relieve the motor by choosing neutral when stopping at traffic lights, instead of keeping the foot on the brake pedal.

It does not sound alright. Your car engine will run at higher speed when you do that (which increases fuel consumption). You stand a chance of being distracted from traffic and ice on road while you are playing with the lever. You cause more wear on transmission when shifting in and out of neutral. My driving instructor said that it is illegal in some states to roll along in neutral. Besides the auto transmission is engineered to disengage the engine from driving the wheels when you slow to a stop.

Your driving method is very poor, and coasting is not legal, as the car is deemed 'out of control'. Go and get some driving lessons from the IAM. Additionally when coasting in neutral you are liable to damage the autobox, for the same reason that you should not tow an automatic, except with a wheel lift.

An automatic trnsmission drive is designed to be efficient over a full range of variable driving conditions.
There is no way that you can beat the efficiency of an automatic transmission by doing it's shifting for it.
You will ruin your gas mileage and also ruin the transmission.

i drive auto - I do not go into N when on a slope because car takes care of that itself, the other 2 things u mentioned - i use them especially the last one - it is a requirement to go into N when stopped in traffic
