GPS directed me onto E-470, I could not turn around because of traffic, got off on the next exit, maybe 1/4 mile. I tried to call saying it was an accident, no recourse. Next thing I know I get a letter from a lawyer saying I owe $30 for using the rip off expressway. And you cannot pay online without pre-paying $35. I have a strong urge to use profanity. I'm certain the majority of positive reviews are fakes.
