Ohhhh, now that is interesting. I think I'd say you don't have an expectation of privacy when you park your car on a public street, people can look into the windows and if they are tinted then using a device to "see" through the tint doesn't go over the line to circumvent your expectation of privacy - if items were in the trunk....maybe that elevates the expectation of privacy but leaving something on the seat or something that can be seen looking into the windows of a car parked out in public seems like you should not expect a high level of privacy.

Your house/apartment on the other hand...you should expect a high/higher level of privacy there, even looking into the windows - if something is found looking into the windows it should not be admissible as evidence without a warrant.

I do not know if the law actually distinguishes privacy if it's a car vs a residence.
