Lane assist

Lane Assist is a device that alerts a distracted driver when a lane limit has been crossed. This is not a warning, but an unequivocal invitation to return to your lane with the steering wheel easing to the right and then hardening to the left. To overtake, you need to be confident and the right decision to stay on course.

Some car manufacturers (e.g. Volkswagen) combine safety signals with additional vibration in the driver's seat to attract attention while driving.
