Uhm, just remember that there's usually a reason why it's illegal to park in some places, e.g. if it blocks an emergency access route.
Be particularly attentive to rough ground (cobblestone), curbs, puddles, lamp-posts or other obstacles.
If your parking passes that test, it generally also accommodates the blind, bicyclists, children, etc.
It's not hard to find spaces that pass the test -- which is also why it upsets me so when people neglect to.
