Sleep Detectors
No matter how many hours you sleep at night or how many cups of coffee you had, it is still not enough to keep you from wanting to doze off when you are on a long trip. If you are just a passenger, then there is no major issue, but once the driver becomes sleepy around the steering wheels, then that’s where the major issue comes in. Many car manufacturers such as Mercedes, Nissan, Volvo, Toyota, and Honda have designed an anti-drowsiness detector that alerts you whenever you have that feeling.

For the Mercedes, the installed Attention Assist system gives a vibrating sensation to the steering wheels whenever it feels the driver is swerving too much and helps to jolt the driver to get the car back in position.
