Hello Harry,

sorry about that . For me it was so obvious you have to drive the car with constant speed so you need to check the speedo the whole time. And I want to build a precise speedo that shows not only the actual speed but the average speed including stops, accelerations etc. Its impossible to drive a constant speed without a closed loop. Its not a straight road to drive but the roads have turns and maybe a stop. And we don´t know wheres the end of
the measured distance so we have to maintain the average speed until the end of the road mission is cleary marked.
So yes, we have to look constantly on the speedo , aybe more on the speedo than on the road.
Regards
