Wait, what?!? That's like saying you'll use more gas if you drive slower because you'll be driving longer. Granted, it's true you may save gas driving slower (less air drag), I do not think the same can be said with exposures. The headlights, being so much brighter than the rest of the scene, will always be that much brighter regardless of whether you expose for a long time with a low ISO or a short time with a high ISO. The same amount of light is hitting the sensor.

For a scene such as that - you need to find an angle where the headlights do not shine directly into the lens. Or, significantly underexpose (ie; expose for the headlights) and then hope you can bring back the detail in shadow recovery. This is where having a good camera comes into play - you can shoot what you want vs only what your camera allows. Now - "good camera" does not mean expensive camera. Just look for a camera with good dynamic range.

With Nikon and Sony you can "push" or underexpose by several stops and then brighten the underexposed part of the image without much added noise. Cameras with poor dynamic range, like Canon... well, just don't take photos like that. Still, though far from perfect, Canon does have a feature (camera setting) that helps protect highlights (bright spots) and is certainly nice to have. No doubt Sony, Nikon and others have that. Check to see if your camera does. If so, it might help.
