    what will the update do?
    how can it tell between and legit sign and a not legit sign.

    A new issue seems to have surfaced - one I had not thought of. Man says CES lidar’s laser was so powerful it wrecked his $1,998 camera | Ars Technica

    To summarise the issue. All autonomous cars use lidar (radar using laser light, usually IR) to decipher their surroundings. The lasers in these are legally required to be low enough intensity not to damage human eyes. Almost all digital cameras are much more easily damaged by high intensity IR than are human eyes. Lidar uses digital cameras - which need to be very sensitive to the IR used.

    Once there are a significant number of these in use on the roads, the Lidar receiver cameras will start to get direct hits from other car's transmitters, permanently damaging part of their image array.

    The solution to this is not obvious, without legal restrictions on the type of Lidar used - for example, 'chirp' lidar does not need anywhere near as intense pulses, avoiding the issue.

    I expect that more "gotchas" are likely to appear before autonomous vehicles make it into general use.

    Id like to see what it could do around Bathurst and what would happen if a roo jumped out in front of it. 😇

    More issues as the US authorities start investigating the tech from car makers - this will undoubtedly lead to regulation of what is required to allow the tech on the road. No surprise Tesla is in the spotlight here.

    For Tesla probe, US regulators seek data from 12 automakers

    Its tech we wont see in our lifetime,not for cars on our roads anyway.

    There are over 700 rules at least that need changing,or modifying to suit autonomous cars on our roads.

    Even the autonomous harvesters they are using in the US cant distinguish between a small child and a rabbit.

    The owners would rue the day they put it on the track.

    I was driving in to town this morning, and thought about how an autonomous car would manage the trip. Some questions -

    • When we come to a gate - how does it know which way the gate opens, to stop as close as possible but leaving room if it swings towards you?
    • How does it pick the least boggy bit of the road?
    • Will it spot that roo sitting motionless in the bushes and that is going to jump out in front of me?
    • How will it know the best track through the water?
    • And can it recognise - that looks too boggy?
    • How does it identify the unmapped and unsignposted turn?
    • Would it avoid the overhanging shrubbery that would pinstripe the side?
    • How will it deal with the stop sign that has fallen off the post in the wind yesterday?
    • Will it manage to reroute correctly where the lanes on Fitzroy Street have been changed using traffic cones to allow for heavy traffic into the covid testing site at the showground, with a flashing sign saying (in dot matrix text) "No Right Turn"?
    • And can it recognise the temporary "shoulder closed" sign and the missing posts marking the culvert where a truck has driven over them?

    There are a few levels of autonomous driving and what you are describing is level 5, and that would probably only be in cities with a lot of infrastructure What Are the Levels of Automated Driving? (aptiv.com)


    • Level 0: No Automation. ...
    • Level 1: Driver Assistance. ...
    • Level 2: Partial Automation. ...
    • Level 2+: Advanced Partial Automation. ...
    • Level 3: Conditional Automation. ...
    • Level 4: High Automation. ...
    • Level 5: Full Automation.
