Hand force: identical
Sensitivity: distinct realization of steering wheel angle
-> no clearance
Shock absorbance: disturbances of high frequency
-> comfort and safety
Automatic self alignment: rest in straight-ahead position
self alignment
Passive safety: steering components are not allowed
to intrude into cabin, air bag

Steering kinematics: no reaction of steering system
during compression (straight-ahead
position, concept later
Width requirement of vehicle: specifications (StVZO 32)
Space requirements: good space utilization, crash
Construction efforts: as simple as possible (economic)
