Use the 2 second rule. Leave 2 seconds between your car and the car in front of you.
It's to gauge the distance e between you & car in front so you have time to stop. You see the car pass a landmark & count 3. If you reach it before 3, you are too close.

Yes because if the car in front of you was going faster, the distance between the vehicle your in and the one in front of you would grow but, if the car was going slower than the speed your going, the vehicle will become closer. :)
A safe distance is one car length for every 10 miles per hour. If you were traveling at 50 miles per hour, one should maintain a distance of 5 car lengths between you and the car in front of you. This safety margin allows for proper time to stop your car in case the car in front suddenly stops. Besides, you will get to your destination no faster if you are sitting on the car's tailpipe in front of you. Back off and enjoy the ride.
it is recommende to keep a gap of at least two seconds behind the car in front of you so the distance varies with the speed
distance by car
double the distance
I am not aware of any statute that sets the minimum/maximum distance you must be from the car in front of you when stopped at a stop light. Most safety experts recommend leaving enough distance between cars so that the you (as the driver) can actually see the rear bumper of the car in front of you.
Whenever a car is run into from behind, in Texas, it is always the immediate rammer's fault. If you are sandwiched, you are paying for the person in front of you. This provides incentive to leave a bigger stopping distance from the car in front of you. Be defensive. It may seem unnecessary, but try to see at least a couple feet of pavement between the front edge of your car and the bottom of the tires in front of you.
The wheelbase is the distance between the front and the back wheels
Because rear end accidents can almost always be avoided by allowing proper stopping distance between you and the car ahead, it is almost universally the fault of the car in the rear. Nothing the car in front can do matters much if the car in the rear is allowing enough distance between them.
