    How is that even difficult ?

    Autonomous vehicles will overtake other ones in exactly the same way as human controlled ones overtake other human controlled vehicles.

    "A self-driving car (sometimes called an autonomous car or driverless car) is a vehicle that uses a combination of sensors, cameras, radar and artificial intelligence (AI) to travel between destinations without a human operator."

    So who's going to decide whether or not it's safe to overtake, and having decided, how can the occupant convince the car that it is? And having decided that, how can the occupant make it happen viz. judgmentally make a timely increase of speed, pull out for the manoeuvre, and pull back in again when it's safe to do so? See where I'm coming from?

    Then they could work harder with extra monay. Saving our planet should be priority one.

    They already have enough toys to play with, and many people think that's quite enough. We have plenty of energy, wind, solar, tidal etc. Smashing particles together isn't necessary, even if it yields a wonderful new clean source of energy, which it probably won't. They can't even get fusion to work despite trying for half a century.

    Yes, but look on the bright side - all the time they're looking for 'the Holy Grail' but not finding it, they've got a job? Blimey I'm so cynical I should be locked up.

    Actually the AV vehicle is far better equipped to make a safe pass than a human being because it has more accurate sensors and can detect things that humans can't. For instance what might look like an open stretch to overtake for a human does not take into account the actual speed of any oncoming vehicles. Humans ASSUME that oncoming vehicles are going about the same speed. What if it is going a whole lot faster that that? An AV can accurately MEASURE the speed of the oncoming vehicle and use that to make a better calculation as to whether there is sufficient space to safely overtake. This works even better in less than ideal visibility because the AV can detect vehicles that humans can't see in those conditions.

    So automated vehicles can most definitely "see where you are coming from" even when you can't.

    Trust you to come up with some fantastical contra-perspective. The point is, would you entrust your and your family's lives to a computer? The other point is that nobody will buy an autonomous vehicle anyway, so the entire subject in all aspects is totally irrelevant; but only I seem to realise it. Maybe I'm a genius but don't know it? :cool:

    As someone who has spent countless hours commuting I would buy an AV in a heartbeat and so would millions of my fellow commuters. Those wasted hours could now be transformed into something productive instead. Taxi fleet owners would buy AV's because it would save them the cost of paying drivers salaries. Anyone who has had to waste time searching for a parking space would buy one because they can just get out where they need to go and leave their AV to park itself and come and pick them up again when they leave.

    There's a big difference between tootling along at just over walking pace in rush hour traffic, and hurtling along a freeway at 30-40 mph, which all other vehicles will be travelling at as well? Autonomous transportation simply isn't feasible, end of.

    Oh ye of little faith!

    Planes fly and even land on autopilot all day and every day and they are doing 500 mph!

    You have probably flown on them and just not been aware that the pilots were chatting up the cabin staff.

    Yes, but there aren't literally thousands of them on the move in a relatively small area, and their movements are constantly being monitored and controlled by ATCs. It's a ridiculous non sequitur.

    Being cynical is a good idea. Before you take advice find out what's in it for them, who's paying them, and whether they have your best interests at heart.

    Obviously you have never seen what air traffic actually looks like.

    If there are that many planes, just imagine how many road vehicles there would be in that same area? Millions is the answer, and none of them being monitored or directed.

    They self monitor and direct themselves. That is the entire point of AV's.

    Planes are actually more chaotic because they are not following marked lanes and speed limits. They are also directly affected by the wind and can lose altitude instantly in an air pocket.

    We're not talking about accident statistics here, we're talking about collisions owing to density, and the impossibility of (dare I mention it again?) overtaking, when all vehicles in the immediate vicinity are travelling at the same speed.

    Two cars smash head on at 120 mph and obliterate into pieces

    One farmer finds a car wing in his field

    Another scientist finds a car wing in his yard but to him it's not a wing , it now a new yard particle and it's his discovery .

    AV's have better collision avoidance systems that humans do. We already established that they are more capable of making safe overtaking passes than humans.

    You can't overtake something which is going at exactly the same speed as you are? Jesus wept!! :wall:

    What makes you erroneously believe that an AV is incapable of accelerating? :wall:

    Yup!

    Some days I found it hard to fathom just how little grasp there is of even basic science amongst the general public.

    You do know that a Tesla in autopilot mode can already do this? If it approaches a car in the same lane travelling slower it will automatically overtake.

    You should try reading up on inter vehicle communication and how this can help with safety and capacity and density on roads.

    The future car will also communicate with other cars so every car will be mapped and position and speed precisely known

    Interesting theory that birds may be able to detect magnetic north by sensing quantum entanglement of electron pairs

    But the poles are moving

    seriously.. Steve Martin was the original get really small guy.. It is very hard to see infinitely small and into infinity in space.. is called timeline.. things matter on it

    If the bords can do it.. our machines can..

    Higgs may or may not exist.. Columbus did not fall over the edge Trump smashes particles all the time

    There is a rather large amount of money being poured into this line of research.

    AS for "wonderful clean source of energy", that is only one hypothetical benefit of particle physics.

    As for fusion yes, we have been working on it for decades now and guess what? all that necessary primary secondary and tertiary technologies are becoming sufficiently advanced, and our knowledge of plasma physics and shaped magnetic field generation rapidly expanding to bring the promise of fusion closer than ever.
