Another zach worth pointing out is that usually their are waaaaay too many handicapped parking spots reserved. You can have a full parking lot with every spot taken except that most of the handicapped spots are empty. This happens quite frequently. In which case, someone parking there without a permit is not really taking away a spot from a handicapped driver.
And another point worth throwing out there is that a lot of people abuse their handicapped parking permits. They get it in some zaida’s name but then use it most of the time when zaida is not in the car with them. (Which is against the permit regulations.) It could very well even be that most of the permit uses are abusive.
Is popa’s shitta that parking in a handicapped slot is akin to parking in front of someone else’s driveway?
