Hormonal Driving in Traffic

Just another wacky working hypothesis: Is it possible to invent a Breathalyzer that measures hormone levels such as Oxytocin, Adrenaline, Testosterone and Cortisol? How do these hormones affect behavior in public, and especially while driving in traffic?

After briefly reading articles about hormones, I came up with this.
The sexuality thing is unrelated.

I'm not even sure if these notes are accurate, these are just hashed out for later focus so I don't forget.

By measuring hormones and neurotransmitter chemicals, it may be possible to deliver a psychological driving risk assessment. A very large survey of samples from accidents must be collected anonymously, only coded test results with related accident information is necessary.

Hey, this might already exist, especially for people who drive trucks for a company.
