Under certain conditions, EOC (Engine Off Cruising) can be done safely. If you drive in such conditions, a kill switch is a good idea.
This ought to do for your 1995 Civic:

suspendedhatch, lots of people seem to be deathly afraid that they won't be able to accelerate away from a possible accident. I'm sure such situations exist. However, in nearly half a million miles of driving, I can't say for sure that I've ever been in such a situation, except during times that I would never consider EOC. The only specific time I can remember accelerating away from danger is during difficult blind left turns where I have to jump out in traffic -- certainly not a time when it's even physically possible to EOC.
DFCO is great if you intend to slow down, but if you intend to keep going, idling in neutral is better. The gas you spend idling isn't as much as the energy you lose from engine braking, which you will later have to spend in gas to gain back the speed you lost. I believe this is mainly because of the extra energy required to pump air and create heat from friction when you turn the engine more revolutions than you would idling in neutral.
Dogbite, is your car equipped with a manual or automatic transmission? If it's automatic you probably should not EOC at all.
