And, lol, yes the 4th amendment extends to driving on a public roadway... roads aren't international waters. Probable cause and such are still important. I recognize what you're saying but -- details matter, dammit.
Details do matter: extensive case law supports a very low standard for privacy in cars and searches on the roadway. Pat downs, being ordered out of the car, free air sniffs via drug dogs, DUI or immigration checkpoints, etc.
Furthermore, just being recorded on a public roadway doesn’t constitute a search or seizure.
The strongest evidence in support of your position is that Boston aerial surveillance case, which is frankly a stupid extension of the idea of viewing = searching, and I’d like to see it or another case reach the Supreme Court for clarification.
