ridiculous. completely ridiculous.
So now what, a homeless person asks for some change, and you are supposed to say, sure, here you go, and put it in this meter. I can only imagine the curse-out you'd get from the homeless person. And who is going to just randomly put change in a parking meter - definitely not people parked on the street since they'll need that change for their own parking space meter!
What a complete waste of $10K. It will take years for these meters to collect enough coins (if ever) to account for $10K - before the meters break, or if you add the additional cost of maintaining and repairing (if they repair them). The most likely result is that they will eventually all fall into disrepair and be broken, rusted, leaning (or laying on the ground) reminders of a terrible idea.
And BTW, isn't it a LOT easier just to donate a small percentage of the existing parking meter fees and donate to homeless causes. duh!!!!
