A scam would be someone who takes money for a cab ride but does not deliver it, or someone maybe who charges an undisclosed fee to unlock the doors at the destination. Uber is not a scam. The user is not being defrauded, nor is the provider.
Confidence trick

"Con man" and "Scam" redirect here. For other uses, see see Con Man, Confidence man, and Scam (disambiguation).
A confidence trick (synonyms include confidence scheme and scam) is an attempt to defraud a person or group after first gaining their confidence, in the classical sense of trust. A confidence artist (or con artist) is an individual, operating alone or in concert with others, who exploits characteristics of the human psyche such as dishonesty, honesty, vanity, compassion, credulity, irresponsibility, naïveté, or greed.
