My late mom had a Blue Badge as she used a walking stick so I do have experience of accessibility issues
Quite frequently I see people getting out of a car with a badge displayed and then heading easily into stores etc after parking in the closest bay.
if you have a reasonable levels of ability within the realms of BB wouldn’t it be more considerate to park in one of the furthest bb spaces in case the next bb holder who turns up is less able?
seems reasonable to me
