This article is mainly focused on the situation where the criminals will have both hands free. It ignores the fact that the vehicles would just stop if anything was blocking the path. Plus, the vehicles could certainly be turned off remotely during an emergency. And nothing stops law-enforcement from having autonomous vehicles that could be set to follow another vehicle with near perfect accuracy.
This is similar to the Tesla stolen vehicle. WHY would the police engage in a high-speed pursuit, risking the lives of numerous people, to catch a vehicle that has GPS in the car and can probably be shut down remotely. Law-enforcement should be partially responsible for the people injured in that situation, in my opinion.
