I personally think the issue with the whole blue badge system is by default it has to be a ‘one size fits all’ system (as any other approach would be impossible to administer) however there will always be people on the edges who it doesn’t really fit.
The lad who sits opposite me at work has a blue badge – not for himself, but due to his wife and 2 kids being partially sighted.
Now, I agree that having duff eyesight doesn’t affect your ability to walk a bit further to the shops – indeed his wife/kids are pretty fit.
His wife has a good job, and as a family they are pretty affluent, so paying for parking is not an issue.
However the one interesting point he brought up when we were discussing this before was safety – in as much as trying to cross car parks/busy roads with 3 partially sighted people can be a nightmare – so any opportunity to park closer and reduce this risk is very welcome.
I’m not sure how the system could be changed/improved without some people who use/need it being disadvantaged.
However, I do think if people are caught using it illegally (certainly more than once) the blue badge should be taken away.
