I have two satnavs in use occasionally and they always agree on speed, and always say I'm doing a bit less than wot the speedo says. That's not unusual. There's virtually no chance of facing prosecution for supplying defective speedometers that over-read the speed by more than the +/-10% tolerance mandated by law but every chance that a speedometer that under-reads by more than the 10% allowance could result in the manufacturer facing a costly lawsuit. I think you'll find that the limits are in fact 0 to +10%, and that it's illegal to sell a vehicle with a speedo that under-reads at all. |

Wouldn't it be simpler just to fit speed governers to cars? We managed it with steam engines, so we know there are no practical problems preventing it. All it would need is the will to do it. Unless is was linked to GPS, how would the governor know what limit to apply? If we can communicate images from Pluto, it cannot be beyond the wit of man to communicate a simple number from something by the roadside to the cars travelling along it, and why couldn't it also be linked to GPS if that would help? In the absence of individual speed limits, a governer with a single limit of 70mph would be better than nothing, but we haven't even bothered with that. With radio speed governers fitted to all new cars, the rest of the system could be introduced piecemeal, as driver discretion would continue to work the same way it always has on roads that had not yet been fitted with the electronic signalling. However, if one was applied, it would have to sense road speed, and not engine speed. All cars are already fitted with a means of sensing road speed. I think it's a legal requirement. The logical thing to do would be to derive the necessary feedback signal from that. My car is 11 years old and uses the road speed to turn up the volume of the satnav speaker above 50mph, so clearly we have all the necessary technology to do this kind of thing, and have had it for quite some time. All it would take would be the political will to put it into effect. "Couldn't be done" is not a valid excuse. We can do anything if we want to. Also, in an emergency situation, it would need to be able to be instantly and automatically overridden if the driver needed to accelerate beyond the limit setting (with maybe an automatic reset afterwards). What sort of "emergency" would justify breaking a speed limit if you're not a police officer driving a car with blue flashing lights? Rod. |

If you are a law abiding driver going over a crossroads with the traffic lights green in your favour, and you notice someone approaching the crossroad at a speed that suggests they will not be stopping at the red light, you can continue to be law abiding and have thr rogue stove in your driver's door, brake hard and be struck in the front wheel area and spin off heaven knows where or you can floor the accelerator and hope to get your back bumper clear before the rogue reaches you. What you can't do is avoid an accident by keeping within the speed limit. I can think of other examples, one of which was a situation I once found myself in, but the one above is sufficient to show that there can be justification. Jim |

Stewart writes What sort of "emergency" would justify breaking a speed limit if you're not a police officer driving a car with blue flashing lights? Very rare - but in my 55 years of driving, there certainly has been the odd occasion when I have needed to "push the pedal to the metal" to avoid hitting someone or being hit. In these circumstances, momentarily breaking a speed limit (which could be as low as 20mph) is a minor concern. [Note that I'm not claiming that these occasions always occurred because someone else was at fault. Everyone makes the occasional mistakes when driving, but the last thing you want is for a simple mistake to result in an avoidable accident.] -- Ian |

Just coincidentally, the cost of the course happened to be the same as the fine (£60) but it was a no- brainer to take this option since it saved me accumulating 3 points on my licence. But you got brainwashed. You only take those if you think you risk running low on points. Not necessarily. If you have points on your licence you will find that changing insurance companies is more difficult and the premiums higher than if you shop around without points on your licence. Don't tell them about the points then. And get them deny your claim when you make one. Never happened. It has actually. Not to me. No point in insuring if they won't pay out on a claim. I don't insure for payouts. There is no other reason to insure. To stop the police from pulling me over. It's you that are liable to the other party if you are at fault, not your insurance company. If they refuse to pay that claim, you get to wear the claim just like you would if you were not insured.
