You're focusing on the wrong part of the post. After the change from point to rope physics, towed cars started behaving very weirdly, sliding sideways every time you turn even slightly, instead of facing the car on the front. This leads to the car getting snagged around corners and poles especially if you're trying to maneuver around zombies. This behavior wasn't present on the previous patch and the towed car would face the direction and follow properly the car you're driving
