People on the next street over (it's a grid) are on Nextdoor complaining about all the traffic coming down their street now. And I'm sure it's the worst of the traffic that's going over there to avoid the features. I'm not sure how the city will fob off spending money on that street after spending the money on this one.
I once lived on a street that was incredibly badly maintained. The city informed the residents that they would be repaving the street and the residents campaigned hard for the city not to do that, for precisely the reasons you're talking about here.
Their campaign was successful, in no small measure because a poll of the residents showed 95% of them opposed the repaving, and that the local paper wrote a big story about the whole affair.
I hate how pervasive this degenerate thinking is in local politics. "we don't want a nice thing because then people would use it."
That's not the thinking at all, though. The thinking is that the road being in rough shape means that everyone is forced to drive at a sane speed through a residential street where children are frequently playing.
In other words, the "nice thing" isn't actually so nice in terms of the things that the people on that street really care about.
The city spent months ripping it up and paving it nice and smooth.
Then a couple months later they put up speed bumps.
We spent a lot of money to get back to the speeds people already drove.
