No. Don't forget what the locksmith said: "Thieves do not pick locks, they break them.".
Like guys going around a parking lot stealing GPS units from cars....
they're not worried if a car is an import or a domestic or what kind of security system it has, all they have to know is that they can smash a window and get what they want.
A U-lock will be defeated by physical cutting/brute force, nothing else matters.
