Question:

What is the best way to figure out how many seconds of following distance you have?

Answer: Wait until a vehicle passes a shadow or landmark, then count the seconds until you pass it.

Explanation
Count how long it takes you to reach the landmark after the car in front of you by counting like so--"one-thousand-and-one, one-thousand-and-two"--and you will have your following distance in seconds. All the other methods are dangerous and will not get you a true following distance. Remember, following distance needs to be increased in traffic, bad weather, for heavy vehicles, or at higher speeds.
