How do people get their windows to defrost so quickly in the winter.?

When I leave work on cold winter nights, it always seems like my windows are always the last to defrost enough so I can see out of them. I blast my defrost on high and it takes forever. I see the other drivers, they don't sc their windows or anything and if a few minutes their windows are crystal clear and I am still sitting there looking thru thick ice crystals!!! Is there some sort of secret or way to get the windows clear quicker. I use the washer fluid that doesn't freeze and everything and I the others don't have remote starters!!! What's the deal???
