I can certify that taxi drivers in Paris casually refuse more than half their rides, based on skin color alone — and openly confess that to anyone, no need to ask — and they have committed enough road infraction in any sitting to loose their driving license for good.
I generally use taxis when I'm late for a plane, so the only thing I could do was call:
- Police department say they see issues frequently, but clients are often foreigners, and unable to testify;
- the head office, G7 (because they need to be named and shamed) reaction was that hiring and paying road criminals was not their concern. After making that phone call several times, I support long prison sentences for the executives of that company.
