The Time Bias, an Example

A scenario to illustrate http://objektorient.blogspot.com/2011/01/benefit-of-driving-fast-deadly.html

Mr. P. drives every day from Meran to Bozen, approximal d=26 km, to work.
Normally he drives down the Autobahn with V1=110 km/h, just the speed limit.

But one day his Boss calls him: "Get down immediately", he shouts, "we have big troubles".
P. puts himself in the car and decides to speed up +30 km/h to V2=140 km/h. He gets a meager ~3 min time saving.

Now he decides to really challenge his destiny and speeds up again +30 km/h to V2=170 km/h. But this additional flooring gives him only ~2 min more.

So in total he saves ~5 min for risking to lose his driver licence or worse. Further, as a rule of thumb, gas consumption is 1:1 proportional to speed. This gives a 5 min gain a huge price tag.
