I'm guessing he's not talking about actual night vision goggles, but of the yellow type glasses that are advertised to protect you from getting blinded by the headlights of other cars and improve contrast.
Since laser protection goggles are made to filter specific wavelength ranges I doubt you would have any benefit from wearing those while driving. Headlights generally emit white light, which means they emit the same amount of light of each visible wavelength. Let's say you use protection goggles for green lasers, which will filter light around the 532nm wavelength. This means only those wavelengths will be filtered from white light, the rest of the wavelengths will pass through.
Results: slight power decrease (I'm guessing less then 10%) and the light will no longer look white since green got filtered out.
