Report bugs here... If you've experienced a bug while playing SC4 that is not listed in the Confirmed List thread, post it here.... Here, there are lots which obviously have street access, but No Car Zots still appear above them. Luckily they do dissapear after times varying from a few days to a few months.
I must admit that bus usage is very unusual in most cities of mine..... some stations have like 15% usage, and others in a similar position have about 200% usage.
