It's not often I drive our Karoq but noticed this morning  the speed recognition carmera had been turned off, so enabled it again. ( I don't have this option on my Kodiaq ). Everything worked as I'd expected until I hit urban streets where there's now a 20mph speed limit. What happens is the camera recognises the sign on the lampost, the central display changes from 30mph to 20mph but by the next lampost the reading has returned to 30mph. It displays that until next 20mph sign where the process repeats itself.

 

I'd have thought the system wouldn't change the displayed speed until advised by the camera but I guess it works in conjunction with the SatNav. Seems if the sign says 20mph and the SatNav says 30mph the system defaults to the SatNav. Doesn't logic suggest it should work the other way round, that the camera takes preference over the SatNav?

 

What a waste of time if the display provides the driver with the wrong speed.

Are these red mandatory signs or green advisories?

Just wait until all the new cars from next(?) month have predictive (and adaptive) cruise control instead of just adaptive cruise control.

 

My Superb only shows the latest speed sign and doesn't seem to chop and change as yours does though.

Mine usually recognises the speed limit sign and sticks with it until it changes... but on motorways it doesn't always read the overhead sign, and in towns can react to a sign on a side street.

Not sure I've ever seen a green advisory speed limit. Just normal red mandatory signs.

My thoughts exactly.

I dobt whether all new cars will have thius feature next month. This type of thing is usually applied to brand new models, not all new cars, and may not even apply to new facelifts. The problem I have with it is that it relys on all models having the samekind of mapping. So if you are driving a car with a certain map and the car mistakenly decides to slam the brakes on because it thinks that it is going into a 30 limit and the car behind hasn't, it's a recipe for a bad accident.

Our cars already have a speed limiter which is a requirement from next month but I think is 2024 when they're talking about speed assist becoming std - that's where the system reads uses the camera. Our Karoq would be like a kangaroo going up and down the streets around here.  

 

They say it will be a requirement from 2024 but not sure if they say the system can be overridden / turned off. I hope it can.

Well, there's one just across the road from me. And another three streets up on this side. They do exist.

My car shows the speed limit on the dash, but I live on a 30 mph estate and it says 20! On our regular trip to Norfolk it says 40 in some stretches that are 60, 60 were the signs say 50 and in Norwich 30 on some 20 roads and vice Versa. Not clear to me if it is the camera picking up signs incorrect or if the maps are out of date.

I can see this technology making cars suddenly brake for example where there is a side road with 30 limit running alongside a 60 main road?

Have to say that excluding those 20mph built up areas, our camera works as well as can be expected ( it'll get confused by the odd lorry displaying a speed limit ). I get what you're saying re: out-of-date maps, but no map designer can account for temporary speed limits etc.  Perhaps I'm just being ignorant but seems logical / obvious to me that the real-time camera should take preference over any pre-determined map.

You don't live in the East End of Glasgow or Edinburgh by any chance? 

 

On a serious note and not wanting to go off subject,  what's the point of an 'advisory' speed limit?  "We advise you drive at 20mph but if you want to drive faster then no problemo?" 🤪

No, not even slightly, and I rarely even venture into the East End, never mind Embra!

 

I treat an "advisory speed limit" as one to follow if children are playing in the street and/or travelling to/from school, but you can ignore it when the street is quiet.
