While at a red light, minding my own business, enjoying the nice day, I heard a screaching sound behind me. A quick glance in the mirror showed a car coming up behind me. Luckily I left room between me and the car ahead and was off a little to the ride side. I was able to pull up on the right of the car just before the car behind me was in the spot I had just vacated. Always leave it in first....if I had to shift, not sure I would have made it.
