Remember when you used to ask people for directions and comedians told jokes about how as soon as they heard the directions, they forgot them?

In a few years we'll think about hailing cabs by whistling or flagging them down in the same way. Plus, the taxi drivers won't be able to bypass particular minorities with quite as much immunity from being caught anymore. "You accepted the hail, we have the record for that, but then decided not to pick the passenger up. Why?"

It is like the floppy disk icon for saving.

Someday hailing a cab will be a button that says "hail a cab" and no more.

There should be a word for this.

Accepting is still optional and you can choose to avoid certain neighborhoods.
