Here is a picture that demonstrates what is so annoying about people who do not think before they park, or if they do, they do it deliberately, which is worse.
As you can see, the disabled ramp is clearly marked by two posts and has double yellow lines next to it. Still, someone has parked right over the one across the road, making it impossible to use.
How ignorant is that?
This was the same ramp that, last summer, I saw two disabled people on electric scooters being prevented from using because someone had done the same thing. The most galling thing was that the offender was elderly herself and just sitting there watching them struggle!
Come on people! Think before you park!
