I have a Dodge Ram.

Now, Although I have never owned a Vette- I have driven several of them.

I cannot say I ever felt more uncomfortable taking a hand off the wheel of the Vette for a moment. In fact, EVERY Vette (Three) I ever drove required a minute amount of LESS attention than my truck does.

I find the Snobbish possibility more likely than the possibility that he is fearful of removing his hand from the wheel. Most sports car drivers drive with only one hand on the wheel anyway. They other has the elbow propped in the window.
