Besides warning you about the fact that you are drowsy, Steer actually wakes you up, so you are safe to continue the journey. Steer bracelet is intended for all drivers and everyone who suffer from sleep deprivation from time to time.
It is useful for long journeys to different city or state, as well as short journeys to work in the morning when you just woke up and still feeling sleepy. Every day, hundreds of millions of people drive their cars. They travel for long and short distances, but very little of them think how dangerous it is to drive while being tired.
Unfortunately, this leads to a shocking statistic, showing that in reality, it is very dangerous, almost as dangerous as driving drunk. While driving drowsy, the driver is very vulnerable to "micro-sleep". Micro-sleep can last for up to 30 seconds, and when it occurs, the driver is unconscious and does not respond to any environmental sensors, such as sound or light.
Micro-sleep is often a result of sleep deprivation, but also often occurs while driving monotonously for a long time.
