Doesn't need to be that sophisticated - Uber already knows who their riders are. Simply cross-reference that list with the publicly listed executives in public companies, and have someone read all the transcripts of their car rides. You'll likely identify at least one Merger and Acquisition deal that you'll be able to front-run for a few million dollars, and this is 100% legal because A) you've notified people that they're being audio recorded so it counts as two-party consent, and B) Uber has no obligation to not trade on insider information that they happen to overhear.
