I like them for driving, especially if it is somewhat overcast and the sun is going behind clouds and then coming back out.
Also, they are typically quite good on hazy or overcast days when there is still a glare - plus, if you are outside on such days, the UV rays still come through the clouds, and it is nice to be able to protect your eyes without having to wear sunglasses that are too dark.
