The E532 is the A7 from Memmingen – Füssen, and exists to have the whole of the German A7 in the E road network. It doesn't enter Austria, but someone edited Google Maps (and OSM, Wikipedia, etc, IIRC) to not have it dead-end at the border but extend logically to E60 and so you got me to investigate it.
IIRC, bogdymol asked why the Austrian E532 is missing and you've drafted it but didn't add it to csv files. I also drove the route and checked whether anything is signed but it isn't.
I thought you mean that "someone" from TM project edited the maps... OK.
However, E roads are not signed in UK at all but are in HB...
I don't like our fuss about signed/unsigned while officially dedicated or not dedicated routes...
