I think you need to do this blind folded. If you see someone is a foreigner you'll believe you're hearing an accent. If you had to do it without seeing them I think you'd find there are plenty of foreigners that have native level accents. I've gotten in taxis more than once at night, gave the guy directions, had a conversation, and then when he finally stopped and turned around to get the fare nearly jumped out of his seat because he was startled he had been talking to a foreigner the whole time. That's happened at least 3 times. I'm not trying to brag, it's just my experience. I know others that can do the same.
