The drivers where I live are amazing! Of all the places I've cycled, I've never come across such friendly, courteous, and good drivers.
They give me ample room as they go by. They slow down as they pass so that they do not kick up any dust, dirt, or snow on me. If I'm waiting to walk my bicycle across the road they will stop for me, even if it is not an official pedestrian crossing. Sometimes if I'm making a left turn across traffic, the whole flow of oncoming traffic will stop for me, even when it is not my turn!! And many will wave, smile, and give friendly little honks as they pass.
If I had to rate the drivers here, I'd say that about 99% of them are excellent.
So, in your area, what percentage of the drivers are actually very good ... be honest now!!
