Seriously, everyone must be thinking it would be awesome to be pissed and have the self driving car drive you home.
Also on my favorites would be "driving" to Perth from Sydney. Not much of a drama really when you can watch TV, eat, sleep, read a book, as the miles pass by. I guess you would have to wake up for the fuel stops, but I think I could live with that. You could do it in record time.
Having said all this, I think the most impressive journey would be the work commute. No problems worrying about traffic when you are in the back having a nap or watching something on TV.

No actually, they did say that these vehicles do require "full awareness" while in use because some input is required for the vehicle to understand it is doing the right thing, and that is not true of being pissed , and not true in some split second emergency in some situations !
economictimes.indiatimes.com/small-biz/security-tech/technology/driverless-crashes/articleshow/56510821.cmsAs a computer programmer myself i can tell you what to look for alike looking for the problem in a black box of an aircraft for information!
Sensors for example only read back what they get, and when constructed the a sensor unit and its specific job is calibrated to quality boundary of reception band.
However, sensors can go wrong as too components can change their values under particular physical environment conditions.
To make matters worse, the information is sent through what is known as a "core" of a CPU which is responsible for sorting, storing and matching data and committing operation upon that data in precedence simultaneously by which in that "scheme" one sensor is one thread (roughly) , and as management of threads in prioritization is called, to stop a thread is called an "interrupt". Prioritisation and backlogging can be a serious problem.
What they advertise in things such as driver-less buses in operation at this time is they have extremely defined routes.
However one of those driver-less buses had quite a slammer "of its own failure" in the past year or two (and others that were not the driver-less vehicles fault e.g. recently in Las Vegas) !
My suggestion is that
someone is sipping coffee at their same destination from same start place half way through your back breaker between Perth and Sydney !

more... (not enough information by statistics as there are very few driver-less vehicles to commit that)

The greatest subtlety about driver-less vehicles and ordinary road accidents by human error is the immense complexity something is trying to "A.K.A." "understand and simulate in real world actions" is really too human a problem for the obscure unique events of environment change. Hazard a guess it would require some extremely human ideals of mind to "understand means to end to traverse some obstacles carefully and sensibly enough" in face of non standardized route occurring or freak weather event
(note - Believe it or not i actually know a vehicle should weigh "2 ton" ( 1814 . 37Kg ) on some good roads to not be blown off the road in good weather with a perfect good surface !!! ).
============== I do not give them the point , it would require a "super cradle computer" to properly assess the information at "time speed" required !
en.wikipedia.org/wiki/Supercomputer
NOT A TRUE LOOK BUT SOMETHING "VAGUELY COMPARITIVE"
one byte is (generally eight bits)
1 mega byte = 1048576 bytes
8 x 1048576 = 8388608 "bits" (one or zero) IN A MEGA-BYTE
120 Kmh = 3333.333333333333 milimeters - p/second
8Ghz (8 thousand million times per second) 8000000000
1/1000 th of a second 8000000
each "bit" (either one or zero) through the CPU instruction core is one cycle unit
THE FOLLOWING WOULD BE CLASSIFIED INFORMATION SO THESE VALUES ARE "SUPPOSE"
A "colour image" of 12 mega pixel can be said to be 12,000,000 x 3 = 36,000,000 (red,green,blue)
A radard image can be said to be grey scaled and 12,000,000 bytes
FOR IMAGING 48, MILLION BYTES OF INFORMATION
Simply to look at the picture will require buffering so to be putting it through the core will mean x 2 for "TIME"
2 x 48 million = 96,000,000 bytes
then interrupts must stop the thread to examine each eight byte set so an interrupt will come with the eigth bit making x 3 for "TIME"
but then the instruction index has to set the CPU core circuit to commit operation on the byte data using the stack and "program data"-CALLED INSTRUCTIONS that are sitting in a separate set of software byte data lcation
so we reach things logically x 6 (much more really) for time to read and operate on the data !!!
48 million x 6 = 288,000,000 bytes of DATA only total = 1728,000,000 bytes x 8 = ( 13824000000 bits (or one cycle beat))
1/1000 th of a second 8,000,000 cycles of CPU core beat
8,000,000 eight million times a "thousandth of a second"
13824000000 divided by 8,000,000
1728 sets of thousandths of a second for data
1728 / 1000 leaves sets of one second = 1.728 SECONDS
3333 (MM Per SECOND) x 1.728 = 5759 mm
================
SOMETHING LIKE .................. (approximately 5 meters traveled with an 8Ghz core CPU)
That's actually "a hell of a long way traveled" in popping the question on the console if something is wrong !!!
5.759 meters traveled (@ 120kMH) to complete the a basic SENSOR RECEPTION AND SOFTWARE PROCESSING !
================
I once figured that my hard disk over a few of hours at 5200 RPM to defrag my disk, the rim edge of the disk at 5 inch diameter travels around 700 Km to complete the task
GIANT suppose but there is some of the problem
The strategy computer scientists use to gain more CPU'S to make a virtual cradle super computer is to Network a set of computers.
