That honestly depends on the girl. I personally see no real reason to have a license because it's unlikely i'll ever own a car, they are expensive to buy and expensive to maintain; even with my current wages it is unreasonable to expect that I'll have a car at any point. And why have a license if you don't have a car? Sure, you can rent them, but if you need to rent them, someone else may as well have their own license and their own car.
But in some other countries where driving is a necessity, I guess it could be a positive thing. You only need ONE person to drive, though. If she has her license, I don't see why you should have to bother if the relationship is long-term.
It might be inconvenient if you live in a country where you are very dependent on driving to get from A to B but other than that I don't see why not. I don't drive myself and neither does my boyfriend it would be nice if one of us could but oh well, we manage.
No, why would you think that? Girls are more into a great personality. If you want to date girls and to make them like you, you should worry about how to treat girls right. You know- be sweet, caring, polite.
