This is similar to what other high-end cars have, lane-keeping and smart cruise control, usable only in freeway-type situations.  &quot;Drivers must keep their hands on the steering wheel.&quot;  Mercedes calls this &quot;Active Lane Keeping Assist&quot;, and has offered it for several years now. Here&#x27;s someone using it with a can taped to the steering wheel to defeat the &quot;hands on steering wheel&quot; requirement.[1] All the major manufacturers have demoed this.<p>This is NTSB level 2 automation, (Combined Function Automation).[2] (&quot;An example ... is adaptive cruise control in combination with lane centering.&quot;) Google is at level 3 (Limited Self-Driving Automation), and going for level 4 (Full Self-Driving Automation).<p>The big problem at Level 2 is keeping drivers from using it when they shouldn&#x27;t. Level 2 doesn&#x27;t understand intersections at all, for example.  Or pedestrians, bicycles, baby carriages, deer, snow, etc. That&#x27;s why the major manufacturers are being so cautious about launching it into a world of driving idiots.<p>Volvo has now officially taken the position that if an autonomous car of theirs gets into a crash, it&#x27;s Volvo&#x27;s fault and they will accept liability.[3] Now that Volvo has said that, other car manufacturers will probably have to commit to that as well.<p>[1] <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Kv9JYqhFV-M" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=Kv9JYqhFV-M</a>
