The past I-don't-know-how-many car2gos I've rented have been disgusting. I have begun rentals only to find used condoms, used band aids, empty mini liquor bottles, fast food trash, and most recently, gobs of snot and boogers wiped all over inside of the driver door and steering wheel!
Whoever you are that is doing this, you're disgusting. These cars are shared. Please clean up after yourselves.
