Hi all
following my earlier post I am following through on my commitment to improve my speed awareness. I have a gadget that measures your speed and compares to the speed limit and warns you if you go over However the speed on the gadget (using gps) seems to show a lower speed than my speedometer so in theory I could go say 34 in a 30 before the gadget warns me, which kind of defeats the object of what I am doing! A quick google though implies that the gps is more accurate that the speedometer so dont worry - is this true?? (Just in case - yes I agree its my own responsibility to keep an eye on my speed not a gadget but I really feel that its an awareness of my speed and changes to speed limits that is my underlying issue (rather than knowing the limit and ignoring it) and I want to use the device to prompt me and create better habits) Thanks in advance |

My car has a speed warning system. It's linked to the vehicle cameras reading the speed limit signage, then sounding a warning alarm when the vehicle exceeds the limit by an amount I can set myself - 1 mph over, 5 mph over, 10 mph over based on speedo readings rather than GPS calculations. What we really need is to link that to the engine management system so that you cannot exceed the speed limit. Or would that cause too much upset to the safety camera partnerships? |

The EU is mandating such a system I think by 2025, how they can mandate something when the technology does not exist yet (and may well never exist) is beyond me. Thankfully their silly rules won't affect us by then. -------------------- If you would like assistance with a penalty charge notice, please post a thread on https://www.ftla.uk/index.php

Thankfully their silly rules won't affect us by then. The technology does exist. I personally dont know how to do it, otherwise I'd have done it years ago. The car can tell you when you are exceeding the limit, cars have speed limiters built into them, either that you can set yourself or permanently with an upper speed limit. Put together and you have the system I'm advocating. Even though we are leaving the EU, you can bet that if such a system is mandatory on EU cars it will be including in UK cars. |

The EU is mandating such a system I think by 2025, how they can mandate something when the technology does not exist yet The technology exists and has existed for a while. The outstanding issue is the accuracy of the speed limit determined for that road, I have a few examples locally where it gets confused by parallel roads or bridges or just data errors. You can back it up/cross reference with sign reading cameras but then I had a car on loan which insisted a 30 sign said 80 every time I passed it (just that one sign, for no obvious reasons I could see). These also exist and are helpful in variable speed limits. -------------------- There is no such thing as a law abiding motorist, just those who have been scammed and those yet to be scammed!

I can imagine some quite complex safety issues to sort out first. The consequences of a such a system throwing the anchors out of a car travelling at 70 mph on a motorway confused with an adjacent 20 mph street, could be quite serious.

Even though we are leaving the EU, you can bet that if such a system is mandatory on EU cars it will be including in UK cars. Under the May government, the stance was that any EU initiative due to start post-transition would be voluntarily implemented in the UK, even though we would be under no obligation to do so. Under the current government that's all gone out the window, there are some directives coming into force in late 2020 / early 2021 and the government has already stated that we won't implement any of the stuff coming into force in January 2021. Indeed one such directive comes into force on 28 December 2020, if it were me for the sake of 3 days I wouldn't have bothered but oh well. In any case I don't see us implementing any EU rules just for the sake of it. On top of this, the system the EU is considering isn't based on GPS data or anything like that, what I heard in media reports is they want cars to have cameras that can read traffic signs. I'm not aware of that technology being reliably implemented by anyone at all, and I don't want to think about how it would cope with fog, snow, default limits that don't require signs and so on.

Hi all
Sorry hadn’t realised there were more responses To answer an earlier point. It can be set to audible alarm when it thinks you are 1 mph over the speed limit |

Mine has a range of settings I can use (absolute or percentage), I have mine set at +10% so still below the enforcement threshold), set it too low and it can get a but wearing.
