Slip road limits
Quote: Unfortunately, it couldn't work out whether a speed limit sign was on the motorway, slip-road. If it is just reading them, it is tolerable. It is no different from the nag on my GPS which cannot determine if it is on the slip or on the main carriageway until they separate by at least a few meters.
Now, deccelerating at each and every 406 junction so the psychotic behind you rear-ends you there and then - forget it. How can this pass for safety is beyond me. By the way - 406 is not a special case, most UK inner town dual (or more) carriageways has similar bogus signage.
