Let's see... I drive a two wheel vehicle with a motor, so I'm not jealous of the freedom and self enjoyment... I exercise with other means, and the amount of road tax I pay for my two wheeled motorized conveyance is minimal...
Anyway, personally, the irritation is not due to jealousy, but here is one of many incidents will serve to illustrate my problem with a certain small portion of the cyclist population.
A number of years back, my family was driving up the San-Cap road to meet our fishing guide to get some fish in the flats around Captiva. Not that it's a two lane road with a 45 limit, and it's a very busy road, being the only way to Captiva. However, we were late despite our what should have been a very ample start because some Lance Armstrong LARPer, down to the yellow jersey, felt he had the privilege to self righteously occupy the road, and not let any of those ebil cars and truck pass. And there was a huge line of cars and trucks behind this moron.
Mind you, Sanibel is covered in nice, smooth, and wide bike paths. But Wannabe Lance thought himself too good for those- even if his pace was best described as "elderly", and 9 year old kids on fixies were passing him on the bike path.
So, if you aren't this jerk, pedal on.
