    Yes, that's a better way to say it.
    Of course, if your autonomous car is 1.7 metres out of position then a head-on smash becomes much more possible.

    That's why DGPS works.. fixed reference points reduce error to almost zero..

    Apart from the fixed reference points improving position accuracy, no autonomous software would place you on the road solely using mapped position..., they all use imaging of various sorts to manage road orientation and positioning.

    So don't worry... you won't be placed over on the incoming traffic side of the line.

    Luckily, Mr Walrus, we don't practice strict topic enforcement here.
    Last I read, the boys in blue could slap you with a fine for driving with your fog lights on when is no fog.
    But I do get your point and thank you for it.
    I must get a light bar with a wide spread for the Camry. I wonder if there is such a thing available.

    When autonomous mining trucks first started operating on a couple of mine sites I was working on in the Pilbara, the "accuracy" of route positioning was so good that the trucks were wearing grooves / wheel ruts into the haul roads as they were all travelling on exactly the same route.

    Komatsu had to re-program them with some variance between the trucks so that the wear on the road surfaces was spread, and road maintenance requirements reduced.

    So the technology to accurately position vehicles on the road has certainly been available and proven for some time - just not so sure about the technology required to ensure that two or more vehicles are not occupying the same GPS location simultaneously.

    I wish they would fine all the little European cars that drive at night with their rear fog light on... it's distracting and annoying.

    Oops slipped off topic again.... my topic GPS is 1.7 metres out....

    I must admit, being a regular driver on that road, I didn't realize there were so many. I'm usually too busy staring at my speedo.
    I passed the scene of this incident 3 1/2 days later. All the pot holes have been filled.
    Pot holes elsewhere on the Glenelg Hwy that have been there for a month or more are still posing a potential danger. There is a really bad one at Lake Bolac.

    An example of this is there are currently almost continuous roadworks for a long distance on the main motorway through the Nudgee area on Brisbane's north side, where it is being rebuilt. At night when the work is happening the speed limit repeatedly varies between 40 km/h and 80 km/h. Sometimes the fixed and mobile speed signs show different limits. Dual lanes narrow to single several times.
    Coming through it last night I spent about 30 minutes constantly altering the speed to adjust to the roadworks limits. It was impossible to use the cruise control as the speed limit changed too often. It was very tiring and required constant attention to the posted speed limit.
    Obviously roadworks are not permanent limits, and it will be great when the highway is rebuilt, so it's a different situation, but I think it still illustrates the problems frequently changing speed limits can cause for drivers.
