Long story short, my sat nav wasn't updated and I ended up on a one way street. Instead of doing the usual 3-point turn, I did a J-turn to be quick (advanced driver). That said, I have to very slightly turn the wheel to the left to go in a straight line. I only noticed it after the manoeuvre. Taking it in for an alignment this afternoon...but I was wondering if it's actually the J-turn that caused this. It's either this or the better half ended up hitting a curb or something, which I don't know about.
