When driving, you should always measure your following distance in seconds. A general rule of thumb is to maintain a following distance of at least 3-4 seconds between your vehicle and the one in front of you. This distance allows you enough time to react and brake safely in case of an emergency.
Following distance is the space between your vehicle and the vehicle in front of you while driving. Maintaining a safe following distance allows you more time to react to sudden stops or changes in traffic situations, helping to prevent rear-end collisions. The general rule is to keep at least a 3-second distance in good weather conditions, and more in adverse conditions.
Yes if you are just following it to see where it is going. It is however not illegal to be going in the same direction as an emergency vehicle as long as you stay 500 feet back. If the emergency vehicle is not using its emergency lights or sirens, and is not stopped at an emergency scene, you can treat it like a regular vehicle and follow it as would be legal for any other vehicle.

No generalized answer can be given. This can be different in every state.
The distance one must maintain behind an emergency vehicle actively engaged in a response, or a pursuit, will vary by state regulations, and even sometimes by local jurisdiction. Fire apparatus customarily has this distance stenciled on the back of the equipment. If it is a law enforcement or emergency medical vehicle you must be aware of your own jurisdictions regulations.Note: Unless you are also operating an emergency vehicle, you may NOT follow one engaged as above. It is against the law to do so in every jurisdiction I am aware of.

Maintain a safe distance between vehicles. Never tailgate.
Following distance is typically measured in seconds. A common rule of thumb is the "3-second rule" where you should leave at least 3 seconds of following distance between your vehicle and the vehicle in front of you. To measure this, pick a stationary object on the side of the road, wait for the vehicle ahead of you to pass it, and then count how many seconds it takes for you to pass the same object.
You should increase your following distance when following a motorcycle. Motorcycles can stop more quickly than cars, so giving them extra space allows you more time to react in case of sudden stops or an emergency.
Thats too wierd.
