I'm sorry that Handyman and others have misunderstood me:
I would suggest that if a speed limit drops from 40mph to 30mph, it is a pretty good indicator that you are driving through an urban area, where you will need to be more aware of pedestrians, slow moving vehicles, side roads, crossings, traffic lights,...........
I neither deliberately break speed limits nor drive faster than I consider to be both safe and considerate in the circumstances. But if it's an unfamiliar road (about half my annual mileage) with no significant change in the surroundings and the solitary 30 limit sign is hidden by a parked van, overgrown bush, or just plain missed in the road-side clutter, my TomTom warns me that I'm breaking the limit. What's the objection to this?
This Government has created a penalty culture of deliberate entrapment to raise revenues. A drastic reduction in the requirements for speed limits signs has enabled traps for 'speeding' motorists to be deliberately created. To justify this, TRRL statistics were falsified to 'prove' that speed is THE major cause of accidents (the actual statistics inconveniently show that in general speed is not A major cause). To paraphrase Dr Goebbels: "If the lie is big enough and repeated often enough, enough people will believe it."
I'd like to keep the clean license I've held for 43 years and well over 600,000 miles with only one (minor) accident in the last 20+ years. Apart from the Xantia, I now drive anything from a 7½T recovery truck via almost any van or 4x4 that you care to name, to a Toureg V10.
This post started out as a reasonable request for any feedback on InfoRad because I can't get updates for my TomTom!
