Police checked nearly 1000 app taxis in Warsaw over one week. 24 drivers lacked any driving license. 4 drivers violated court-ordered driving bans. 600 of 997 controlled drivers were foreigners. Foreigners included illegal residents and fake document holders. 4 wanted Schengen fugitives caught: from Pakistan, Zimbabwe, two from Uzbekistan. 166 fines issued totaling over 48,000 PLN. 14 driving licenses seized. 71 vehicle registration documents confiscated. Stricter Polish license rules fail to stop illegal foreign drivers in taxis.
