When jumbo jets are safely landed by computers I think it's pretty obvious that the necessary technology exists to drive a car down the road.
Not necessarily.
Jumbo jets have a fairly limited set of conditions and parameters to deal with. Another plane is not going to suddenly decide to change lanes without looking, or stop short in front of you, for example.
While technically those situations do arise, rarely, they are almost always FATAL even if the aircraft is being flown manually. By and large commercial aircraft control keeps a safe distance between planes and gives each plane exclusive rights to the runway as it is taking off and landing.
In a car you have a near-infinite set of variables to deal with. Kid pops out from between two parked cars chasing a ball. Some idiot tries to change lanes and occupy the same physical space as you. Guy ahead of you has a blowout, skids into the barrier, and starts flipping end-over-end... Just a few examples.
The situations you mention present some of the challenges the autonomous vehicles are faced with. The autonomous car will not be programmed to just follow rules....see this ..do that. Instead the computers are being developed to have a form of artificial intelligence. The fully autonomous cars will not be controlled by a smart phone.
I personally don't see how these will work except on major roads and urban areas! Many secondary roads have poor markings and difficult intersections.
It is a PITA when your cruse control acts up, it could become real big PITA if the autonomous driving feature failed!
Those with current versions of autonomous cruise control that slows if you come up on slower traffic, what happens if someone cuts in front of you!
The adaptive cruise will brake hard if needed. Probably faster than you or I could. I own a 2016 Subaru Outback with the eyesight system and it is pretty amazing. It is NOT a self driving car. What it is provides a suite of safety assist features that do remove some stress from driving. As humans we all make mistakes driving and elsewhere. These systems make these observational mistakes far less likely and in some cases make us better drivers. I know many here are perfect already but for the rest of us this is awesome use of tech. What it won't help is another driver being an idiot. That is the stuff of scifi.
