Taxi app Uber have quietly slipped out an update to their legal policy, banning their driver and passengers from carrying firearms.

UBER FIREARMS PROHIBITION POLICY

We seek to ensure that everyone using the Uber digital platform—both driver-partners and riders—feels safe and comfortable using the service. During a ride arranged through the Uber platform, Uber and its affiliates therefore prohibit possessing firearms of any kind in a vehicle. Any rider or driver found to have violated this prohibition may lose access to the Uber platform.

How are they going to defend themselves from cabbies now?
