It was not a suicide!
The guy was drinking the night with his friends and they dropped him off on a parking lot next to the motorway. He took the wrong turn and drove in the wrong direction but not against the traffic. Just towards the wrong exit.
His friends noticed and called him that he was going the wrong way. He turned around, now AGAINST traffic. And this is when it happened.
He was very drunk at the time of the accident. Young German resident with Greek background, 21yrs old I believe.
So, no suicide. Just a very tragic accident.
