This does bring up an important question about autonomous driving aids. How do they account for emergency vehicles ?
Say the 7 was driving through a solid green and making a turn but the police van needs to cross a red light with sirens on, how does the car know to stop in time and in a safe way ?
It seems it would only work if the police car also has car to x communications on board to tell the autonomous car to stop.
Seems rife with problems. Too many points of failure. Too many avenues for hackers to commandeer a persons car.
Let's keep autonomous cars away just a bit longer
