Drivers have been warned that police could remotely 'hijack' your car to limit your speed from anywhere.
Clever anti-alcohol interlocks on cars are already able to override a vehicle to stop a driver who has failed a breathalyser from taking the wheel - but technology is set to go even further.
Tesla boss Elon Musk claims the driverless cars he is developing will be so safe that drivers will be able to sleep at the wheel while their vehicle navigates autonomously.
But the next frontier for 'smart' driving tech could go much further.
An expert is predicting authorities will in the future able to hijack tomorrow's cars remotely - even while you're still at the steering wheel - to slow down speedy drivers.

Experts at a US tech firm have reportedly told a conference at an Artificial Intelligence (AI) event in San Francisco how police could soon be able to take control of speeding cars.
Qualcomm's Nakul Duggal predicts the smart cars of the future will become so cleverly interconnected that cars will be able to be linked into roadside infrastructure that can talk to speed-limiting systems, the Sun reports.
The company is reportedly already working with top car makers to provide technology to connect future smart cars to one another.
Duggal explained an advanced speed-control system could theoretically work by installing the necessary technology into roadside infrastructure, such as street lights.

A combination of cameras and radar installed every kilometre could be used to track cars' progression.
The roadside sensors could catch out rogue drivers captured driving too fast or making illegal lane changes, Duggal reportedly explained.
That information could then be automatically registered with police databases, and ultimately could see authorities being able to tap into smart cars to slow them down.
The expert explained the backbone for such technology already exists.
The Sun reports Duggal explained how the ability already exists for AI technology to communicate to a vehicle what actions to take.

“So if there’s a speed limit requirement due to congestion, this is something that can be managed through infrastructure,” he said.
Authorities could even get the tools to halt you driving completely, if they are able to discern you are unfit to be behind he wheel, he continued.
“Driver monitoring…is useful from a safety perspective,” Nakul reportedly said.
“The alertness of the driver is critical. Is the driver impaired? Is the driver in the best health?
“If not, the car will be able to drive itself and take it to a safe area where it doesn’t impact other cars.”

He told reporters an AI system could take the roadside technology and cross-check it it against GPS. If there is no coverage in the area, the roadside tech captures and car's inbuilt location systems could be used to pinpoint its location is down to 10cm of accuracy.
While such tech could be useful to combat dangerous driving like speeding in the future -Duggal reportedly warned China is already moving in that direction, and America should not necessarily follow in its footsteps.
International disquiet is growing over China's embrace of AI systems like facial recognition technologies and social credit punishment-and-reward regimes to develop a mass surveillance state.
