Exactly that. It’s pretty much impossible to police properly. However, is it Motabiliy’s duty to police it? Or is it the DWP’s. I’d argue, it’s very much the latter’s because they after all, are the ones handing out OUR money. Which is probably why it won’t ever be done.
I’d argue it’s other family members who should report fraud. It is not the fault of DWP or motability if family members turn a blind eye to misuse. All these people complaining about their neighbour’s auntie’s monkey’s uncle who gets a car despite running marathons have a duty to report it or shut it. They’re calling for a vital service – Motability to be removed from all disabled people because of misuse of the few but don’t report the actual misusers themselves.
