Sometimes my GPS thinks I'm on an adjacent road, especially when I'm on the freeway. Seems like that kind of error would be catastrophic in combination with a system like this. Also, what's the rationale for letting people go 10 over the limit? That's effectively admitting that people go 10 over the limit, and it's OK.
- nimfan 3y agoText of the proposed law [1]: "28171. (a) Commencing with the 2027 model year, every passenger vehicle... be equipped with an intelligent speed limiter system." and (b) "be capable of being temporarily disabled by the driver of the vehicle." Also: (c) "shall be capable of being fully disabled by the manufacturer or a franchisee, but only as provided in Section 28172." (28172 is about EMS etc.). I smell loopholes for me (politicians, and likely techies ;-), but not for thee. Also interesting how GPS jammers haven't entered the chat yet?

- m-p-3 3y agoThe car speedometer will estimates the vehicle's speed by measuring the number of revolutions per minute of one of the wheel or its transmission. If the car has different-sized tires than the ones it was originally designed for, there may be some discrepancies between the actual speed vs the speedometer readings, which is why there is some leeway in the speed limit to account for that margin of error.

- gnicholas 3y agoIs it technically legal to exceed the speed limit when passing? Don’t get me wrong, I’m not saying no one ever speeds. I’m just wondering what the reasoning would be in this case. Seems to reify speeding, if anything.
- kirubakaran 3y agoSome good anecdotes here: https://www.quora.com/Have-you-ever-been-pulled-over-for-going-1-MPH-over-the-speed-limit-If-so-did-you-get-a-ticket https://www.quora.com/Have-you-ever-been-pulled-over-for-goi...
- gnicholas 3y agoOof, that one about the misidentified blue Camry sounds maddening.
- tjohns 3y agoNo, it's definitely illegal, at least by the letter of the law. But as long as you're only going a few miles over the speed limit for a few moments, nobody's going to write you a ticket for it. One of many situations where the law in theory and practical application differ, since officers are given discretion (read: ability to apply common sense) in their duties. It's not a perfect system, but it's what we've got.
- chiph 3y agoNot in my state. And probably few, if any others. But it is a safety thing. The longer you spend in the oncoming lane completing a pass, the higher the risk of a collision (cars pulling out of driveways into the lane, people misjudging distances, etc.). There's also what I've observed (not sure if there's an official name for it), that if you pass someone slowly, they will "lock tractor beams" onto you and start to match your speed. So you want to have a noticeable speed difference between your vehicles to prevent this.
- cameronh90 3y agoAre blind spot mirrors not mandatory there?
- tjohns 3y agoMirrors or not, hanging out in the blind spot is a dangerous place to be. You don't want to be there for any length of time longer than absolutely necessary.
- tjohns 3y agoAlso, safety. Being able to floor it during an emergency can sometimes get you out of an impending crash - if the situation is right, and your reaction time is quick enough.
- gnicholas 3y agoOh for sure, but that could require going more than 10 over the limit. I can't imagine needing to go 25 over the limit under pretty much any (non-apocalyptic) circumstance, but 10 doesn't seem like sufficient for this type of situation.
- quantified 3y agoRe 10 over: As-written and as-lived are quite different. You'd see the governor turned out in the next election if he signed that bill. Michael Dukakis lost his home state of Massachusetts in the presidential race after he sicced the state police on drivers for exactly this during his campaign. The law says to stay stopped at a stop sign for 3 seconds, and signal turns 800 feet in advance on the highway too, 600 feet on streets. (According to family who had their driving tests recently.)
- JackeJR 3y agoMeasurement error of tools used to catch you speeding?
- gnicholas 3y agoI understand why cops would have give leeway, but here the measurement tool would be your speedometer. Although I’ve heard some manufacturers make theirs a little on the slow side, I’d think they’d be pretty accurate in general.
