A road network does need to be consistent. It's not an exact analog, but it's kind of a "weakest link" situation. It's needlessly dangerous and frustrating for everyone to have to deal with bad infrastructure, even if it's just one weird street that everyone still has to cross.

I have one on my way to work. I just get off my bicycle and walk because the alternative is going trough a tonne of traffic in an intersection of two highways.
