I&#x27;ve driven a volvo with this feature and it has two modes, one is below 50km&#x2F;h where it will fully control the car and can do quite hard turns to follow the lanes and cars in front of it. Another is above 50km&#x2F;h which requires hands on the wheel but the actions are not as strong, it is more like driving on a very concave road which automatically directs your wheels towards the center of the lane, if you don&#x27;t resist the motion of the wheel it will keep you in the lane. Not keeping the hands on the wheel in the second mode will trigger a warning after a few seconds and later disengages the system.<p>Essentially you just need to hold your hands on the wheel and relax your arms. Before you&#x27;ve driven with this feature you might not realize but all the time when you are driving you are constantly doing minor adjustments to the steering wheel which takes quite much effort, both attention and physically, this takes away all that but still keeps your brain in the <i>&quot;i am in control of the car&quot;</i>-mode. If you were to keep your hands off i think it&#x27;s easy to zone out and if something happens there might be too much context switch for you to handle the situation fast enough.<p>Is there any video of the tesla doing this at highway speed? I can only find city driving.
