Pretty clearly the longitudinal wind would be more than canceled out by drag. You might be able to get some net power from any cross-wind that is present. But for that, you’re better off with fixed windmills used to charge your battery.
I saw a paper that suggested that for big non-aerodynamic trucks you could put a big fan on their back and power it with the fuel and save something like 20% on fuel.
