Inquiry into accident

Basically when exiting my apartment building. I scraped a car parked right at the edge of the driveway making a turn when oncoming traffic forced me to turn into it. The rear passenger side door scraped their bumper creating scuff damage. My car got a gash. Left a note, and my insurance sided with them. However, the car by Seattle law was parked within 5 feet, in fact like six inches into the driveway!. Which I think is illegally parked. My question is, thought my insurance sided with them. By law, isn't that car supposed to be parked outside 5 feet so I can adequately get the hell around it. Should I take them to small claims for damage to my car and premium adjustment. I know this sounds....pathetic. But isn't that the purpose of the 5 foot law, so people can get around it without having to avoid oncoming traffic. I will admit their is No sign or even curb paint to show that it was not allowed to park so close...
