Don't get in private cabs! It is illegal and DANGEROUS. A friend's former maid (Filipina)got into a private taxi with her friend ready for a night on the town and they were abducted by the 'taxi' driver. One girl escaped the moving car, being badly injured in the escape, the other was brutally raped. Getting into a unregulated taxi is taking too big a risk, no matter how few and far between Karwa taxis may be.
