Johannesburg, South Africa: As gunshots and explosions rang out when looting and mayhem continued in many parts KwaZulu-Natal on Monday morning, major routes were closed to traffic, Durban's public transport system was not operating and even funerals had been put on hold. Protesters continued to loot shopping centres on Monday morning. Some were seen walking off with appliances, including TVs and washing machines, and trolleys filled to the brim. Reports from Pietermaritzburg indicated that Brookside Mall was on fire. Police and private security companies battled to disperse protesters from Friday when the protest action, themed #FreeJacobZuma and #KZNShutdown on social media, saw violence erupting across the province. It has since spread to Gauteng. The entire N3 Toll Route, in both directions, from Harrismith in the Free State to Cedara in KwaZulu-Natal, was closed to traffic as “a result of the current spate of uncontrollable violent attacks on road users, trucks, security and emergency services and businesses”.

Of course, Forbes barely scratched the surface of what kind of control there is over vehicles, but the article is still quite revealing.

2017: "Indeed, court documents reveal a 15-year history of what's been dubbed "cartapping," where almost real-time audio and location data can be retrieved when cops order vehicle tech providers to hand it over. One of the more recent examples can be found in a 2014 warrant that allowed New York police to trace a vehicle by demanding the satellite radio and telematics provider SiriusXM provide location information. The warrant, originally filed in 2014 but only recently unsealed, asked SiriusXM "to activate and monitor as a tracking device the SIRIUS XM Satellite Radio installed on the Target Vehicle for a period of 10 days." SiriusXM told FORBES it complied with the order and did so by switching on the stolen vehicle recovery feature of its Connected Vehicle Services technology, which is only available in a subset of cars it supplies (the satellite radios alone cannot be tracked as the telematics services can).

It was little surprise to find General Motors (GM) had repeatedly worked with cops to hand over not just location but also audio, where conversations were recorded when the in-car cellular connection was switched on; its OnStar service is one of the best-known telematics providers on the market.

In 2001, OnStar competitor ATX Technologies was ordered to provide "roving interceptions" of a Mercedes Benz S430V. It initially complied with the order in November of that year to spy on audible communications for 30 days, but when the FBI asked for an extension in December, ATX declined, claiming it was overly burdensome.

Cops can go further than simply surveilling a car too. In numerous carjacking cases, police have been able to turn off a car's engine to recover the vehicle. For instance, in 2015, police were able to locate and shut down a stolen motor in Camden, New Jersey."
