The simulation step-length is a technical limit to the reaction time of all vehicles in sumo. If you set a low enough step length you can use a very low tau without having to worry about unsafe driving. The default tau is 1 (which is also the default step-length). See https://sumo.dlr.de/docs/Car-Following-Models.html#model_parameters
