What is the optimum trailing distance for a car? - optimum car wax
If two (2) The second rule is universal, it can go further, but only for speeds of movements of the city (60 km / h), approximately 35 miles per hour. As the speed increases should also include the time between two fixed points, so that when the time you reach 55 mph, a difference would be like 4 to 5 seconds.

Optimum Car Wax What Is The Optimum Trailing Distance For A Car?
6 comments:
It seems that there are two general views: 1 car length per 10 miles per hour, or 2 seconds.
What is the difference? For the sake of argument, assume a car is 15 meters (the figures are much worse, only 10 meters).
Then at 30 MPH:
- For the standard length of the car, you need 45 meters between you and the vehicle ahead
- Typically 2 seconds, then you would have 88 feet between them.
At 30 mph you drive 44 meters per second. Press the car length rule is only 1.02 seconds to realize that you, and then stop, the brakes.
At 60 MPH:
- For standard-length car is 90 feet between you and the vehicle ahead.
- For the rule of two seconds, is 176 meters between you and the next vehicle.
At 60 mph you travel 88 meters per second. Rule specifies the length of the car is still only 1.02 seconds to react and stop.
If you allow only 10 meters, then react 0.86 seconds to win.
The second rule 2 gives you double the time to understand what is before you and to answer.
Most coaches will need 125 to 150 yards of 60 km / h, the brake to stop as hard as possible. Granted, that are rarely available with a fixed obstacle while driving on a road, but I would have preferred to 176 meters between me and the next in its path, instead of only 90 meters or less.
In addition to lack of space by the domination of the car to another problem with this rule, that many people are very poor in judging distances. Walk outside to find a clear signal, like a tree, the wall of a building, whether on foot, until you think you are 90 meters away from the object. Thus, the accurate measurement of the distance. If you are within 15% of the 90-foot (what was that 77 to 103 meters) and numeracy skills are probably above average.
It is much easier to count two seconds.
Space is the key - the more you have to give you a safer driver - because the room gives you time to interpret, understand and respond. And I agree with the other respondents - more HIGK m speeds, even two seconds, can not really sufficient.
You use the two seconds rule. If the car goes a bit further, is more than two seconds to go in there.
There is a minimum
a point on the road section 1 1thousand 2 1 miles, if you insist on this point before you 2 1thousand then are too close
You need to accelerate at least one car length behind the car in front of ten miles per hour.
ex. 40 mph = four car lengths
I think it's like two maybe three car legth to be sure.
