some people will never understand and at this stage i think its pointless.

Lets have a look at two examples of parking in a disabled person space

if you make 30k a year, have no savings, $100 is major expense.

if you make $1m a year, $100 is just a vip parking space.

Both people should be equally de-incentivized to illegally park in a disabled people parking spots. The proportional fines are the only way to get close enough to that state.
