did the city streets ride to Dorchester this morning then downtown then back to Dorchester then back home for the long commute day (32m)

On the way home tonight I was cutting behind Fenway park and came to a four-way intersection, I had the stop sign, no one else there but me and I look and a cab is coming down the road to my left and we approach the intersection at the same time and as he has no stop sign I begin to slow down and he flashes his lights and waves me through. A CAB waved me through! I don't know how it is where you all live but this is somewhat unheard of here in Boston. I gave him a big thank you salute as I went through the intersection.
