Because people are halfwits. Big deal if you post a pic of your car or the tags and so what if half of Australia now know what you have in your garage.... it's not like you stated underneath the pic ... HEY.. I live at number 666 halfwit parade, twitsville and never lock my garage.

A bit like the numbnuts that won't tell people the reserve price on Ebay auctions..... WHAT is the big bloody secret about someone knowing the minimum price you will take for something... jeez, it's not like it's a 5 million dollar mansion or something ..... no... it's normally some rusty piece of crap and they're probably embarrased at the rediculous price they are asking..... twats....
