Death Taxi

A taxi or cab company that is notorious for hiring dangerous drivers; making it safer to walk to your destination than to ride in the cab from that company. Death Taxis sometimes offer lower rates to counterbalance the fact that you are risking your life to an unsafe degree by getting in the car.

Gerald: No! I've ridden with them before, and I always end up with a Death Taxi!
