Would a driverless car really be ideal to use as a get away vehicle? You would be stuck in a car that obey's the speed limits and rules of the road. Hardly useful to dodge the cops.
Clearly that section is based on the question 'assuming car software could be modified in a way that made them violate the Laws of Robotic Cars, what new dangers would that pose.' Just like the bit that mentions the trailing car assumes they would have a way to know where a car is going in the future, suggesting a way to query a given car for it's direction.
The first isn't an outlandish question, modifying locked down software isn't exactly a new art. It wouldn't happen for a while likely just due to the small reward to the difficulty of execution.
