On my way back from Vienna in March I saw an ambulance from IL (Innsbruck-Land) not far from Kerpen near Cologne on a parking lot.. I followed it more than 1,5 hours to Aachen and E314 through NL until Leuven in Belgium where I had to turn off. Spoke to the assistant driver on that parking, he said they are bringing a Belgian ski accident victim home with a broken and plastered leg! xD
