I guess maybe not so much straight up terrible as... uh, reckless. Wait, I have the quote somewhere, let me dig it out.

This is Jeremy Bonderman speaking: "I absolutely will not ride in Justin's car. He drives crazy-- he has that need for speed. He loves his Porsche. I think I value my life a little more than he does right now."

And then this:

SN: Are you a speed junkie? A former teammate said we should ask you about your love of fast cars.
Verlander: I'm not one of those people who buys a car and just sticks it in their driveway. If I buy it, I'm going to drive it. I'm not saying it's bad that some guys do this, but I'm not buying a car for $200,000 just to bring it out 35 years from now.
SN: Where do you take the Porsche to drive fast?
Verlander: (Laughs.) Uh... the track? It just depends when I feel like going fast. I try not to get caught.
SN: How fast have you been able to go?
Verlander: 175.
SN: Where?
Verlander: Don't worry about it.

From a Sporting News article, iirc. Someone posted it and I saved it, because lol.
