  • In 59 crashes examined by NHTSA, the agency found that Tesla drivers had enough time, “five or more seconds,” prior to crashing into another object in which to react. In 19 of those crashes, the hazard was visible for 10 or more seconds before the collision. Reviewing crash logs and data provided by Tesla, NHTSA found that drivers failed to brake or steer to avoid the hazard in a majority of the crashes analyzed.

    NHTSA also compared Tesla’s Level 2 (L2) automation features to products available in other companies’ vehicles. Unlike other systems, Autopilot would disengage rather than allow drivers to adjust their steering. This “discourages” drivers from staying involved in the task of driving, NHTSA said.
    “A comparison of Tesla’s design choices to those of L2 peers identified Tesla as an industry outlier in its approach to L2 technology by mismatching a weak driver engagement system with Autopilot’s permissive operating capabilities,” the agency said.
    Even the brand name “Autopilot” is misleading, NHTSA said, conjuring up the idea that drivers are not in control. While other companies use some version of “assist,” “sense,” or “team,” Tesla’s products lure drivers into thinking they are more capable than they are.

    It is not a single crash. There are assisted driving system out there using pupil tracking, to make sure drivers are still paying attention.
    Tesla’s solution is something along you need to be resting at least one hand on the steering wheel. And don’t get me started on how they are diluting the concept of “full self driving”…

    But yeah, you’re right, the only reason I’m sceptical of Tesla’s semi-self-driving tech; is because I think Elon is an egomaniac little bitch, who is incapable of ever admitting he was wrong in even the smallest way.




  • I’m no electrical wiz, but it seems like we’re dealing with a misunderstanding?
    When I hear “3 phase support”, I jump to it can be powered by at least part of a 3 phase supply without transformers. Which is what they clearly state in multiple sources:

    SAE J3400, with the support of a supermajority of OEMs, has made sound engineering decisions that will pay dividends for decades by lowering barriers to electrification in North America. … It supports AC voltages commonly available in commercial areas, streets, parking garages, and dense housing locations, specifically 480/277-V three-phase power, one of the most common configurations provided by utilities in the United States.

    I am not sure I understanding you correctly, you wanted them to feed all 3 phases to charging EVs? Batteries are DC, wouldn’t that mean sticking a heavy 3-phase to DC converter in the car?








  • Everyone else is saying vinegar, which will certainly work.
    But if you’re like me and cannot stand the stench of vinegar, then I recommend citric acid. 2 tablespoons to a liter of water is a good place to start, but you can most likely find dosage specific to your machine with some googling.
    Also, you can get ~2kg of citric acid for 15~25 $or€. I use it to descale everything from coffee contraptions, to shower heads; and a big bag of it lasts us 1½ years. Our water is fairly hard too, about 160 TDS.


  • It is a combination of how tall the front is, and if it sweeps backwards a bit, or is practically perpendicular to the ground.

    What matters is how likely a pedestrian is to be pulled under the vehicle, instead of pushed up onto the hood. You can have a fairly tall grill, if it is angled backwards somewhat. And it won’t be a near instant death bulldozer for pedestrians.
    Tall and flat is the most dangerous combination, and that is exactly the trend of most big and giant trucks & SUVs.
