While there is undoubtedly abuse of the system, I think we should be wary of jumping to conclusions without knowing the whole story.
If you look at the rules for blue badge use in England (
http://www.direct.gov.uk/prod_consu...disabled/documents/digitalasset/dg_186198.pdf) you'll see that it does allow for use by a disabled person
as a passenger. So sometimes, yes, you will see an able-bodied driver fetching or dropping off a disabled person, who could have been inside the shopping centre.
If use is by an able-bodied person without the badge holder being there, then that is against the rules and offenders should be prosecuted. This is from the rules leaflet:
Who can use the badge?
The badge is for your use and benefit only. It must only be displayed if you are travelling in the vehicle as a driver or passenger, or if someone is collecting you or dropping you off and needs to park at the place where you are being collected or dropped.Do not allow other people to use the badge to do something on your behalf, such as shopping or collecting something for you, unless you are travelling with them.
• You must never give the badge to friends or family to allow them to park for free, even if they are visiting you.
• You should not use the badge to allow non-disabled people to take advantage of the benefits while you sit in the car. Although it is not illegal for a badge holder, or a non-disabled person waiting for the badge holder to return, to remain in the vehicle while the Blue Badge is displayed, consideration should be given to using a car park whenever possible.
