Destroy All Humans! Path of the Furon Help

I know what a lot of you are thinking: "What in the world are the crash test dummies, statues, records, nails, and lava lamps?" Well what they are are the collectibles that you see when you pause the game. It will say something like 5/30 or 17/30 or how many you have. There are a total of 30 collectibles on each map and a total of 150 in the whole game. In some places like Shen Loooooonnnnnng, you need to use your ability to stop time and put a car in midair. Then fly up and land on the car and take off again. For the tallest building in the game, you will need to take another car with you. Even with your jetpack completely upgraded, you can't make it to the top.

Here is a link that I found online that has maps of collectibles and where to find those DAHM acheivments:
