As you say of insurance: anyone that owns an insured motor vehicle knows that the insurance does not prevent vandalism of any kind. As that be why there be the insurance business.
But I speak about the ones who have the intent/behavior of demanding one's such possessed item.
What stands out (no sic, no exagg) about the 'bike share' is that the bikes are in an open environment.
Why would I want to have interest in such a business? I would not.
The reason why the climate may seem good for now is because of the economy is not as depressed as earlier.
But once the economy gets back into its schizophrenic depression: the 'bike-share' businesses need more caution against those wanting something-for-nothing.
