  1. Are we sure they can't fit 35 inch tires?

    I think itā€™s been said that on full lock bigger tyre/wheel (sorry; tire/wheel) combos would foul on something.

  2. Bidirectional home chargers

    To counter the point about aging,I heard something, probably in one of the Fully Charged videos, possibly from Nissan, that the profile of discharge in a vehicle to grid situation is very different from that when driving (of course) and can actually help to preserve the life of the battery - my...

  3. GMC Hummer EV teaser video - 1,000 HP and 11,500 ft lbs

    I donā€™t think itā€™s black and white - youā€™ve got to have a little from Column A and a little from Column B. Yes governments are great at taking dumb ass solutions, but some regulation to enforce a certain standard is needed in some cases.

  4. Even just a 1-5 mile per day solar panel would be handy

    Minor detail ;)

  5. Even just a 1-5 mile per day solar panel would be handy

    Or the Lightyear One?

  6. Pardon the temporary look while we renovate

    Actually, I notice that the pictures do show on my phone in landscape, but not portrait, so I guess itā€™s a viewable-width thing.

  7. Brake Lights

    I too donā€™t know, but the part of the system that is commanding the motor control to go into regen could also command the brake lights to come on when the level of regen requested exceeds some level. From a Functional Safety point of view though, it would be easier to argue the safety goal of...

  8. Pardon the temporary look while we renovate

    Ah, Iā€™m on mobile. Itā€™s the only way I consume most forum traffic. Would be nice to see the pictures on mobile if possible... gives me something to look at for the next 5 years before I get one for real...

  9. Pardon the temporary look while we renovate

    Is it just me, or are we not seeing the background images that cycle through stock images at the top of the page?

  10. Tesla's Hardware 3 computer frightens legacy auto

    I was going to quote the same passage. The move to fewer ECUs has already started, admittedly higher up the supply chain, with OEMs developing ā€˜domain controllersā€™ that replace multiple ECUs. So the vehicle will have fewer controllers, and more communication between those controllers and...

  11. Rivian Eventual L3 and Data Gathering

    And actually that reminds me of the _only_ thing Iā€™ve heard RJ say that I didnā€™t _completely_ buy in to. I think it was the Sean Mitchell interview in the cable car, where RJ said something about L3 (I think) and said ā€˜youā€™ll be able to read a bookā€™. For me thatā€™s L4. The most memorable way...

  12. Rivian Eventual L3 and Data Gathering

    Agreed, except that for Level 3, the requirement for the driver to be able to take over essentially means you do need to pay attention. Yes, you shouldnā€™t need to make the decision to take control, but if the vehicle asks you to take control you will need to do so pretty quickly. If the driver...

  13. Rivian Eventual L3 and Data Gathering

    Simplest and most robust, yes. But that wasnā€™t the question. The question was is it possible to learn more quickly than having a fleet driving a billion miles, and the caveated answer is yes, not the ā€œnoā€ you first gave. Rivian will be doing as you say, but they can also be taking advantage...

  14. Rivian Eventual L3 and Data Gathering

    I didnā€™t mean to suggest that there is no AI in the control part, no. I realise you could reasonably deduce that from what I wrote. Now clearly I havenā€™t written any part of the Tesla system, but I do have relevant knowledge. To have one amorphous system that perceives the world and directly...

  15. Rivian Eventual L3 and Data Gathering

    But there is an important distinction here. I would agree with you (that you canā€™t learn from someone elseā€™s data) if the AI system was directly controlling where the vehicle was placing itself in lane etc. But itā€™s not. The AI system is understanding the environment and deciding where the...

  16. Rivian Eventual L3 and Data Gathering

    I have to disagree; the hard part of the problem is understanding the world, not navigating through it. The teenage son (or daughter...) doesnā€™t crash because they turn the steering wheel incorrectly - itā€™s because they donā€™t fully comprehend the situation.

  17. Rivian Eventual L3 and Data Gathering

    By the way, if any of you have 3 hours of your life to give away, this is worth a watch: Note the OPā€™s request not to derail from topic, so I only post this as a good source of information about how these types of systems work. Note that the first hour-ish is just footage of a Tesla driving...

  18. Rivian Eventual L3 and Data Gathering

    But Tesla annotates the image data with information about where the road goes etc. So you can apply your own algorithms to the image data and correct the algorithm if it doesnā€™t get the right answer about where the road goes. Edit: agree though that making the car do the right thing for that...

  19. Rivian Eventual L3 and Data Gathering

    Depends what is meant by ā€˜dataā€™. If one bought access to the source data (the streams from cameras and other sensors) then different algorithms could be applied to that data. That could be useful. Of course that would mean probably Peta bytes of data so is probably infeasible, but technically...

  20. Rivian Eventual L3 and Data Gathering

    Just came across this that mentions one way of reducing the length of time teaching an artificial intelligence based system takes: Havenā€™t watched it all yet.
