a good minute after the breakaway group has passed and with the peloton just 10 seconds out, an ambulance with flashing warning lights and sirens on, suddenly enters the race course... and is now de facto part of the race (after following the race course for a few kilometers, it will eventually leave the course and will have had no influence on the race itself)
