I never realised how much we were being short changed with Sat nav in UK. In Southern Germany I got traffic alerts. One was warning of traffic incident with pedestrians on highway 11 km ahead. 1km tailback, no faster alternative. Second was motorway closed ,automatically diverted me onto side roads. (Preplanned closure with diversion signs ) third was warning of animals on carriageway. Saw a small deer happily grazing the wrong side of deer fencing. It could have been a hazard, but not on the level of the sign I saw later on the Egnatia Odos motorway in Greece.
See photo.
Yet the uk we have to do without. Not sure how it gets signals , radio waves, phone signal,or from the satellite,? and whether this service will expire if I dont renew a subscription. I'd rather put the money towards data and use something like waze. (athough I dont want to be alerted every time someone spots a bunny rabbit.
)
Also I noted the car not only reads speed limits signs that are there but some that are not. It once showed 30 kph signs with stars. Presumably for winter conditions. I double checked, there were definitely no signs displayed . It must also use memory and GPS .
