Ok, Thank you very much. This works indeed now.
In this case though the parameter changed is the tau as far as I see. To create a similar behaviour by changing the reaction time, I am experimenting with action step length as suggested in: https://sumo.dlr.de/docs/Car-Following-Models.html#actionsteplength (tau is not reaction time, I am aware of that.) Would you say that there is a minimum difference between step-length and actionsteplength to have a behaviour similar to the one of the example? Thank you very much.
