1. Does it save gas to put the car in neutral when coasting and at stop lights?
i doubt it. your car is still gonna be on. you may go down like 200 rpms, but that wouldn't be saving that much gas.
2. Is it safe (if you keep your foot on the brake)? Is it safe to turn the car off at a light?
shouldn't the car shut off anyway?
3. What help and damage could it be for the trans. to be changed to neutral and back to drive?
i doubt it would help and i don't know if it would do any damage. i don't know anything about transmissions.
4. Overall, is it a good or bad idea to put an auto. in neutral in any of these cases.
i don't think it would hurt the transmission, but over time, it may wear it down quite a bit.
those are just my thoughts, if i'm wrong let me know.
