**4. Critical Analysis of the Results**

Based on the results of the experiment, it was possible to demonstrate that in terms of quality indicators, such as the criterion of deviation from the route line and "yawing", ECO steering wheels are less functional both in the "route" and "slalom" test. It was also possible to demonstrate (however, for only one muscle group) that the use of this steering wheel causes greater muscle fatigue. The authors of the experiment are aware of the need to conduct research that will enable them to broaden their knowledge on this subject, i.e.:
