Later generations of night vision are designed to limit the amplification of bright sources of light. FLIR is an even better type of night vision that shouldn't be as susceptible to bright sources of light.

It's particularly distracting in the snow, or when ice has formed on the windshield. Finally, it reduces night vision by constantly becoming brighter as you approach a light, and dimmer as you retreat from it. It would be safer, and certainly cheaper and less wasteful to not have street lights.
Pedestrians can carry a flashlight, and on most nights, the moon and stars provide enough light to navigate by, assuming a street light hasn't ruined the eyes natural night vision.
