Yes, he has abused his wife before, sending her threatening text messages for almost a year and even paying her an unexpected visit, ignoring his restraining order and supposedly hitting her whilst at it. I’ve seen and heard a lot of reports by people claiming he’s the most arrogant shitbag you’ll ever get to meet in a lifetime, plus he CLEARLY has an anger problem.
To answer the question what he’s been up to after Formula 1… practically nothing on a professional level. He wanted to join Dakar this year, but didn’t manage to get his truck license in time.
It’s a shame really, being Dutch I was a fan and I really think he did have the talent, just lacked the right cars and the right management… and, perhaps, the right attitude.
