Radar would not detect a Styrofoam wall either the return from Styrofoam is extremely low. Radar also can not distinguish elevation differences very well so an overhead road sign can be mistaken for a stopped vehicle or a stopped vehicle mistaken for an overhead road sign.
Are you really going to sit here and deny global warming when you can literally see it with your own eyes these past 20 years?
Everyone says 2024 was one of the hottest, I didn’t notice, spring didn’t have many hot days and either did summer that I recall. I coach track in the spring and summer and take note of hot days. I don’t remember the 23/24 winter and certainly don’t remember the weather from the last 20 years. I have to “trust the science” for that kind of climate analysis. So no I have not seen it with my own eyes and unless you have been logging your own weather station for the last 20 years you have not either.
It’s getting harder to believe that climate change is threat and not a grift when climate activist act this way.
You’re partially right, stationary objects on the side of the road will have a different Doppler shift than a stationary object in front of the vehicle, items on the side of the road can be filtered. Cheap radars with low sampling rates will not be able to distinguish as their Doppler bins are fairly large.
