The Volvo City Safety uses laser radar, or LIDAR, to track the distance and speed of the car in front of the driver. The windscreen mounted device renews its calculations 50 times a second, pre-charging the brakes to avoid potential collisions before drivers can even sense the danger. Link.
The Mercedes Distronic Plus uses a form of radar to maintain safe distance from neighbouring cars. The short-range 24 gigahertz radar sweeps a fan-shaped 80-degree pattern with 30 meters of range, while the 77 gigahertz radar sweeps a nine-degree pattern at a far longer range – combined, the radars cover 145 meters of road.
