I'm lazy and I have big trucks so I usually do it the cheating way where you drive in forward and drive up on the curb until the back tire touches then turn and get the front off the curb and you are perfectly parked against the curb without any backing up. Only works with trucks though obviously as small cars dont do well driving up curbs. It's definitely illegal but I'm construction I do what I want do it right in front of a cop then put a cone down somewhere random next to it and he's like "oh hes a worker its cool."
>rob store
>put down cone
"he's a worker its cool"
>shoot someone
>put down cone
"hes a worker its cool"
>rape small child
>leave chopped up bits of small child in a ditch
>with a cone
"its cool guys, no need to investigate, he's a worker"
