This script is used for fun to create a small dataset my personal usage to visualize based on the collected data the police distribution over time.
example output:
This script uses Waze's internal API (scraped from https://www.waze.com/livemap). Judging by the data service uri (
.../il-rtserver/...) - the results are filtered to Israel. If you wish to find an additional data services, try visiting https://www.waze.com/livemap and use web-dev tools for inspection.
