Are you implying that a bunch of code written for carefully and precisely observing traffic law (driverless cars move like a bus driver shuttling a pope made of glass) with the assumption that the usage environment is simplified by said law (moving in simple lines, road markers, etc), is [a bunch of code which is] going to perform superior to humans in the unpredictable and dynamic environment of a getaway?
I'm willing to accept that this technology could be exploitable or unsafe. It could, just maybe, have a marginally useful application in crime. But I'm not seeing it here, and I'm not expecting it tomorrow.
If anything, LE should be delighted at the idea of remote control, surveillance, etc. when cars are on TIOT.
