I'm not sure what influence the Minneapolis City Council has over the state legislature anyway. I suppose if the liberal, cycling happy City of Minneapolis thought it was a bad idea the bill would die that much more quickly.
As far as passing it goes, I don't think luke warm support from the city has much value so I'm doubtful this will make it through. The council vote was 7 to 6 in favor. I can't imagine suburban and rural legislators liking the idea. I doubt they see the need and would rather error on the side of safety.
Would be nice though.
