Trish, I agree with Sydney's last post. You probably have a bike that is too small, and hence too short, which makes overlap worse. If you can't get the dealer to get you a larger frame, you'll need to live with overlap, because I think 160 cranks is an extreme solution.
I have overlap on two of my bikes, but only when turning at low speeds. Over the years I've learned to position my crank so it does not get in the way. I certainly appreciate how hard it can be in traffic, when you need to think about everything other than your feet. But the alternatives are pretty extreme. Especially going for a fork with more offset: that will have a major effect on how the bike steers, and move it toward a twitchy feel that will require all your focus.
So to learn this new skill, you will need to practice.
