Power Steering.

 Power Steering works to make steering less work for the driver.  This means the driver should be able to turn the wheels of the vehicle when it is stopped, while the engine is still running.  For many vehicles, power steering is standard.  Truck drivers benefit from this as well.  The first power steering system was the 1955 Chrysler 300C with the optional “Hydraglide” steering system.  Power steering is steering with a hydraulic assist.  Power steering created a whole generation of people without much upper shoulder strength!
