So, have done 80 trips in my 1st 5 days, mostly in the Chicago downtown at night, where GPS is spotty and I don't know my way around very well. 63 trips were rated, 57 five stars. Rating is now at 4.91. What concerns me is the downward trajectory, my first trips I did in the suburbs, at 5 stars, 24 out of 25 trips. Don't appear to be hitting it off as well with the urban dwellers. My car is fairly nice but really old 2001 Infiniti i30. Am I off to a bad start with ratings?
