Connected cars and the Internet of Things are actively leveraging the safety on roads both for drivers and pedestrians. Integrated IoT technologies help the driver monitor surrounding conditions and react to the changes, or even take full control of the car in emergency situations. Now, most cars have their safety features as built-in options (like Advanced Driver-Assistance Systems), but the extra services such as automatic speed limiting or blocking texts can be implemented by plugging into the on-board diagnostics (OBD) port.
