Brainwave measuring technoloy to prevent drowsy driving

This is footage from a traffic camera close to a road block that's causing a slowdown of traffic.
But we see a truck failing to slow down before crashing into the truck ahead, leading to a multiple car pile-up.
No brake lights suggests the driver's attention was somehow compromised.
In cases where trucks swerve across lanes or drive through highway guardrails, drowsy driving is often the cause which also leads to a higher risk of casualties.
According to data from the Korea Expressway Corporation, in 20-20 and 20-21, the number of deaths caused by motor vehicles came to 350 of which 251 were due to drowsy driving.
Technology that could monitor a driver's attentiveness could significantly reduce such accidents.
Now, in a world first, Hyundai Mobis has developed a system that monitors the driver's state by measuring their brain waves.
The technology uses a sensor that looks like an earphone.
Worn on one ear, the driver's level of attention is detected by changes in their brain waves and the driver is alerted through both the ear piece and their mobile phone.
"Artificial Intelligence learns brain wave signals and patterns. Based on an A.I. analysis, if the driver is not focused, an alarm or some other function will alert the driver and wake them up."
This technology was tested on 60 drivers in the last year.
Results show that instances of drowsy driving and careless or negligent driving decreased by up to 30 percent.
"Driving on the highway for long hours, I do get drowsy. Then there's an alarm that wakes me."
Hyundai Mobis plans to expand the testing for this device to 300 bus drivers this year.
With more data to feed the A.I., the technology can be even more detailed.
The company says this device is more advanced than technology used by overseas competitors that monitors changes in the drivers' pupils or pulses and hopes to commercialize the earpiece in the next two years.
