Note two words absent from the OP: &quot;Speed limit&quot;.<p>This machine will keep pace with traffic.  OK.  Does that mean it will break speed limits?  Unless it is scanning for each and every potential road sign, it simply cannot be respond to arbitrary&#x2F;temporary limits.  The determination of the legal limit on a piece of road is a complex task.  Road construction, local conditions, sunrise&#x2F;set, time of year (school zones) and even weather can be a factor.  And let us not forget &quot;Speed limit X when children on road&quot;.  You need some serious cpu time to work out whether that person walking along the road is a schoolgirl or a construction worker.<p>Imho any system not capable of determining the speed limit accurately is a legal liability.  Have fun with the tickets.<p>&gt;eliminating the need for drivers to worry about complex and difficult parking maneuvers.<p>No.  Parallel parking is not a complex nor difficult maneuver.  It is total beginner territory.  No lives are at risk.  With a decent bumper, even risk of property damage is minimal.  Anyone not capable of learning to parallel park probably shouldn&#x27;t be behind the wheel of much anything.  Anyone buying this car to avoid such mundane tasks isn&#x27;t someone with whom I want to share the road.
