PageSpeed Insights not happy with G-Maps, Doubleclick and G-Analytis

[Sven Grossenbacher]

Hi, 

How am I supposed to use Browser Caching for pages I do not host... 

On a website I just optimized for PageSpeed, it asks me to use Browser Cache - for three Google products: Maps, Doubleclick and Analytics... 

Why is Google itself not following their own standards? Or is there a way I can influence the time of Browser Caching for those scripts?

Thanks
