I'm a solo bicyclist, never been a Lance wannabe so haters can move on.
I may need to make a presentation to my town council regarding "sharing the road".
Most drivers are very good at sharing but nearly all take chances when passing me.
They ALL cross over the midline in an abundance of caution even though I am always inside the fogline but some do so on curves

.
I have been scolded more than once even had a few objects hurled at me but that's in the very small minority.
I've requested an appearance in order to ask that I be permitted to post a letter on the township website. Part of that memo is a calculation of how long it actually takes to pass me. I posit that there's no need to endanger themselves by crossing the line, they only need to slow down and make the pass.
Here's the math; t= Da + Db / Sa - Sb; units are D= feet, S = feet/sec
If a car starts to pass me at Da = 30 feet behind and resumes normal travel at Db = 20 feet ahead all at S1 = 25 mph and my speed is S2 = 10 mph then it would take the car 2.3 sec to pass me.
Did I get that correct?
