  • While braking suddenly is something that can happen on the roads, it’s still a potentially dangerous maneuver. It’s often better than the alternative (crashing into something/someone), but there’s still risk involved.

    If these vehicles are doing panic stops frequently and unnecessarily, that’s a major problem. It’s a common type of insurance fraud, for starters.

    I wouldn’t be surprised to find that the computer has a faster initial braking response whereas it takes time for peoples’ feet to fully depress the brake pedal. A shorter time from the brake lights coming on to the brakes being at full service pressure.







  • It can also include situations where the worker isn’t paid what was agreed.

    For example, if you were going to have a 10% commission but the employer lowers this to 2% or nothing, or where a $30/hour rate magically becomes $15/hour after hiring.

    They might legally be able to cut your pay by giving notice - this will depend on the jurisdiction. In other regimes, they essentially have to go through the full legal process to fire you.







  • Yeah, NZ & Aus both have a ‘standard drinks’ system.

    My guess is that larger quantities of alcohol (particularly bottles of spirits but also wine) simply aren’t intended to be drunk by one person in one sitting. Total volume of alcohol isn’t that useful; it’s more useful to be able to work out how much is in one shot or one glass.

    This is especially important when you look at the same product being sold by the shot/bottle/cask/barrel, or being able to buy a gallon of it in your own container historically.





  • In user manuals, legal documents and communications with federal regulators, Tesla has acknowledged that Autosteer, Autopilot’s key feature, is “intended for use on controlled-access highways” with “a center divider, clear lane markings, and no cross traffic.” Tesla advises drivers that the technology can also falter on roads if there are hills or sharp curves, according to its user manual. Even though the company has the technical ability to limit Autopilot’s availability by geography, it has taken few definitive steps to restrict use of the software.

    Tesla told NTSB that design limits for Autopilot would not be appropriate because “the driver determines the acceptable operating environment.”

    He said Tesla could easily limit where the technology can be deployed. “The Tesla knows where it is. It has navigation. It knows if it’s on an interstate or an area where the technology wasn’t designed to be used,” he said. “If it wasn’t designed to be used there, then why can you use it there?”

    In a sworn deposition last year first detailed by Reuters and obtained by The Post, Tesla’s head of Autopilot, Ashok Elluswamy, said he was unaware of any document describing limitations on where and under what conditions the feature could operate. He said he was aware of some activation conditions for Autopilot, including the presence of lane lines, and that it is safe for “anyone who is using the system appropriately.”

    Tesla’s commitment to driver independence and responsibility is different from some competitors, whose driver-assistance technologies are loaded with high-definition maps with rigorous levels of detail that can tip vehicles off to potential roadway hazards and obstructions. Some manufacturers, including Ford and General Motors, also only allow the technology to work on compatible roadways that have been meticulously mapped.

    Over the years, NTSB has repeatedly called on NHTSA to rein in Autopilot. It also has urged the company to act, but Homendy said Tesla has been uniquely difficult to deal with when it comes to safety recommendations. Tesla CEO Elon Musk once hung up on former NTSB chair Robert Sumwalt, said the former chief, who retired from the agency in 2021 when Homendy took over.

  • Hmm. They’re very common in NZ now, however it appears that document is talking about modulating the actual normal shop lighting, not just an independent transmitter.

    I redid the electrical in a supermarket already fitted out with Pricer gear, and we went from dumb electronic-ballasted fluoros to dumb-driver LEDs, no DALI and certainly no comms uplink or modulation smart enough for that. I’m aware that the document suggests power-line communication to the drivers, but these were off the shelf dumb drivers/ballasts.

    The ceiling mounted Pricer transceivers would have been doing all the transmitting, and as I never saw any visible light coming out of them, and the HF ripple and instability from the shop lighting would have been significant, I think it’s pretty safe to say they were using some form of IR.
