How can a driver-less car break the speed limit? Surely the maximum speed is set by the program designed into the vehicle. Aren't there going to be lots of wonderful sensors to detect speed limit signs, online connectivity etc to allow the vehicle to download lots of data which the vehicle will then use to determine where it is, traffic conditions, posted legal speed limit and then determine the maximum speed allowed?
As to payment of fines for a speeding AV: If the program allows speeding then it is the program's manufacturer's fault. If the program has been 'modified' by the owner then it is the owner's fault (or whoever modified it on behalf of the owner)?
