No Parking Past This Point

On my street they have the No Parking Past This Point (or something like that) sign, but so many people can't seem to read. Either that or they think as long as part of my vehicle is still before the sign then I'm ok. But no, I'm pretty sure that's not how it works. Why can't people just obey the darn signs? It doesn't take a rocket scientist to understand them. Most kinder gardeners could explain these signs! Sorry it just really bugs me.
