I use mine to go to work as long as the weather permits about 8 miles each way. It costs me 14 dollars a month gas. Here is about $5.30 a gallon. I get about 130 miles to the gallon on my last count.
I aviod busy streets and highways side strets only. the drivers here are nuts, I had one guy in a dilevery truck cut me off and give me the finger mostly because i pased him at an intersection.
But otherwise I have never has a negative reaction to my biike. I have driven past the cops but i cut off the engiine and pedal.
