Why Google maps can be crap at times

[trevskoda]

The one thing I don't like about Google maps is that I've been unable to set up audio alert for speeding.

I have 2 gps speedos mph klh in van and they beep like bonkers along with my £24 satnave, sometimes so loud they blank out my wifes nagging.

I set the vans speed alert to 30mph.

You do know there’s signs along the road that tell you the speed limit?

They’re not hard to see, big round things, white with a red edge and a number in the middle.

I am very aware of signs that indicate the legal speed, but I do like a gps that warns me if I've inadvertently exceeded that speed, or if I've maybe missed a sign, and I'd much rather be watching the road and not a speedo.

The signs are beside the road your so carefully watching

If you drive to the GPS displayed speeds, you will be at least 2-3 mph below the actual limit. The issue you would have if it did alert you is that they are not accurate, so it would be pointless or worse still, get you 3 points and a fine.

I use a tomtom with speed limit warnings as an addition to reading the speedo, I have found it to enhance my awareness of speed limits, and no I don't rely on it to be foolproof. I and many others have found a gps to give a more accurate speed indication to most speedo's, where I've checked all my cars but one have shown a higher speed than the actual speed.

Provided you speed is constant, and you are not going up or down a steepish hill, the speed displayed on GPS is pretty accurate.

What happens when you go into a 20 zone near schools etc.

There is so much street furniture these days which distracts from looking ahead.

Yes, more accurate by design, vehicle speedos have to read too high.

Not here, 1 mph over and you have to go on a speed awareness course costing you over £80, 10mph over and by by licence for at least 3 mths and points.

Where it goes wrong is going down a steep hill or climbing one, the gps sees you as moving forward slow where as you may be doing over the limit.

I find it interesting that having driven for a living most of my life, both nationally and internationally that it seems that in the last decade that suddenly drivers can’t see the road and need a devise to make their decisions for them.

In 1991 I took a load from Stockholm to Marrakesh no sat nav, no speeding ticket. Back load was to Istanbul, then back to Peterborough.

Didn’t need a satnav then, nowts changed

Do what everyone else does near a school, park in the middle of the road, tend to your hair and do a 15 point turn.

Provided you speed is constant, and you are not going up or down a steepish hill, the speed displayed on GPS is pretty accurate.

The actual error on hills is remarkably small, on a 1:5 hill it's 2%, so if you where doing 60mph down a 1:5 hill your actual speed would be 61.2mph, on a 1:10 you would be doing 60.3mph.

It warns you of speed cameras though. It warned me the other day on the A66 but I was too busy gabbing and ignored it and passed the Camera doing 80.

I always turned the warning off on the TomTom. Got on my nerves.

Thanks for working that out, my we brain would have exploaded trying.

You need to get out more

Back in 1980 we drove around most of Europe with just maps that showed only the main roads, so what, it doesn't mean I don't embrace technology to make my life easier.
