Do you really think there will ever be a 100% driverless car? I find it highly unlikely. And the paradox is, the better self-driving cars get, the more trouble

Do you really think there will ever be a 100% driverless car? I find it highly unlikely. And the paradox is, the better self-driving cars get, the more trouble driver is in when they are forced to take over. Drivers will be lacking basic driving skill, and essentially will get stuck on snowy/gravel/flooded roads.
