2 or 3 per block seems excessive. I would think having a corral on alternating corners is more than sufficient. (By alternating, I mean you'd have one every other block on each street, and you'd stagger the streets. For example, if Bryant/25th had a corral, then Bryant/26th wouldn't, but Aldrich/26th and Colfax/26th would.) That way you're never more than one block from a corral. If you can't walk a max of one block from a corral to your destination, you probably can't ride a bike, either.
I still prefer docking systems, but if dockless is really gonna happen then this seems like the right compromise to me.
Definitely want to see dockless stations downtown on everyblock down Hennepin, Nicollet, Washington, 3rd Ave, Park Ave, and Portland Ave at least! Then every other block at least on all the other bike lane routes downtown.
Then out in the single family household areas ever 2-4 blocks seem reasonable depending on area bikeability and biking data. I don't mind walking a few extra block TO the bike station but if I have to walk 4 blocks to the bike station overshoot my destination and walk another 4 blocks then what the heck is the value of it? Nice Ride has tons of data on the major bike routes. I'm confident they will eventually get it right. The first phase this year is only the beginning so I'm sure it won't be to full sized rollout just yet. It seems like this year the goal is to prove to the city we are responsible enough to NOT abuse the system and leave our toys.. um. I mean BIKES laying around everywhere! I seen several scooters blocking sidewalks in ways that I feel a conspiracy is afoot. NIMBY's must be moving them in hopes to piss off city officials to ban them.. I'm just hoping we are able to prove how NICE we truly are and are able to prove to the city we are responsible enough to have NICE things!
I will have to save my rant about how they need to make sure we have dockless stations all along the midtown greenway as well as other greenways which are outrageously empty of bike shares. It's a very important east west route and we only have ONE station along the greenway! I wanted to stop off at the bike shop along the midway the other day but the station was not an option so I couldn't! Again maybe a conspiracy as keeping nice rider users out of bike shops might be good way to retain customers but I doubt that is the case.
