Courts have previously held that heuristics based determinations are not sufficient to serve as probable cause. E.g. "predictive policing" technologies can be used for e.g. scheduling officers to different areas, but aren't valid to conduct a search. If this feature is used to make an arrest, there's a good chance the case would be thrown out.
The heuristics are clearly about who to pull over, etc. Evidence for arrest/search will be determined afterwards. And, as far as search is concerned, it could be as simple as getting a dog to bark.
