Hi,

how can a fly be in mid air in a moving vehicle and not be pushed to the back?

Yes, you will see some slight difference, but not much as the reduced speed of the engine causes the torque converter to reduce the torque on the engine when you are completely stopped or slowing down or braking, so it just basically maintains a fluid connection but not like when you are accelerating or driving.

Shifting into neutral releases all the energy stored in the torque converter, leave it in gear so you don't have to rebuild this energy. Gas savings is unnoticeable.

what will happend if i don't go with car for emision test?

Ok there is good and bad to this I have wonderd this too and studied the answer as it will save a very small amount of gas however the valve body on your automatic transmission wont be able to handle that constant neutral to drive type thing it will wear the valve body on yout transmission becasue it shifts with vacume pressure so unless your car is from the 70s and gets 12 m.p.g and you wont care to junk it go for it if. If you want to save yoru self the costy repair in the near future just suffer with the small increase in fuel economy.
