My wifes Si has the push button folding mirrors (button by normal mirror adjusters) which never gets used. They don't fold by holding lock button on the keyfob.
One thing that some people don't realise the Jazz has is 'superlock' on doors, where if you press lock button on fob again within 5 seconds of first push the doors 'superlock' and cannot even be opened from inside the car by the door open handles, so even if someone smashes the window they can't get doors open.
