Yeees. But some of the guidelines are confusing. So the basic rule is that you have to keep a "2-second distance". This is the distance you vehicle would travel in two second without breaking. The Formular is 2x(v²/100). But at lower speeds its a completely different calculation. And when you are waaay faster you are supposed to leave half your speed in metres as a gap. Then there are separate rules for fog and long vehicles and multiple vehicles that drive in a row on one lane roads and all that.
There are also rules for the distance you should keep to the cars and especially bikes next to you and they are different depending on if you are in a "place" or outside of one :)
That formular is wrong. The correct formular is (according to the official TÜV theory test questions):
2x(v/10)x3 (well technically they only calculate it for 1 second so I added the 2 infront).
That is, at the same time, slightly more than half your speed meters.
Your formula looks like the formular for the "Bremsweg" with a "2x" added infront but thats not how it works because time is not a variable there...
Wait no. So I'm Shure I got the Formular wrong, but there is one that is specifically for the distance covered per second. And of course time is a cariable because how else would you define speed.
Yeah, that formular "(v/10)x3" gives you the meters you travel in one second.
Your speedometer tells you how many km you travel per hour (km/h) and using that conversion you get the meters you travel per second (m/s).
