My first inkling would be to tell you put an aluminum baking tray under the vehicle next time you pull into the garage to collect the water. Put the water into a sterile glass bottle and take the sample to someone nearby with a Mass Spectrometer. Is there a local community college or University with a Chemical Science department? At first glance it looks like some form of metal oxide such as aluminum oxide, calcium oxide, zinc oxide. Could also be some form of salt. Where is it coming from? Is it all coming from the car or is there some type of chemical reaction with the tile you have on your floor. You might need to seek out a chemist, chemical engineer to figure this out. Condensate is just water vapor that has change it's phase from atmosphere vapor. Do you live close to the ocean? Do you get the same white powder if you left the car on some other nearby surface that is not moto tile?
