...if I'd trust my tripmeter.
The tripmeter has not worked for couple of years now but today it decided to start moving again, and move it did!
When driving on highway I noticed that the ring that measures 100s of meters travelled spun around about once a second, thus my speed was 100 meters per second which is 360 kilometers per hour.
Oh but it did not end there.
While driving at city it started spinning about 4 times per second = 400 meters per second = 1440 kilometers per hour.
And then the acceleration.
When standing at red light the tripmeter was still but immmeadly when I started moving I again went 400 meters per second = 1440 kilometers per hour. So instantly from 0 to 1440 kilometers per hour.
On the way home tripmeter died again.
