An interesting topic. Personally I welcome the advancement in autonomous vehicles. We already have plenty of inolvement from technology in most modern vehicles. Don't get me wrong I love driving but as the cause of most accidents are the drivers, take them out of the equation. Autonomous cars would stick to the speed limits, use the correct lane around roundabouts assess the stopping distances correctly, be able to accelerate into a gap more accurately, know their width through a gap, will not be distracted by children in the back seat, etc.etc. As for taxi drivers most of them should have their licences revoked. Admittedly software can be hacked but a terrorist could hijack a fuel truck easier.
