I think that you are being overly sensitive and are just looking for anything complain about!! They have the same right to mhe road as you do!!
No, actually they don't IMO. I pay for those roads when I get a license plate and then my tabs. I pay at the pump. They don't. They use that road at my expense.
The speed limit is the max speed you can go. It doesn't mean you have a right to go 60 under all conditions. Besides that's a false start since bikes do not go on the freeway.
There are plenty of 45MPH.50MPH roads I've seen that allow bikes. Also, in most states there is a law about blocking traffic. If you're going under the limit and are blocking 5 cars or more (in my state)
(1) No person shall drive a motor vehicle at such a slow speed as to impede the normal and reasonable movement of traffic except when reduced speed is necessary for safe operation or in compliance with law
On a two-lane highway where passing is unsafe because of traffic in the opposite direction or other conditions, a slow moving vehicle, behind which five or more vehicles are formed in a line, shall turn off the roadway...
Furthermore, there's this clause:
Every person riding a bicycle upon a roadway shall be granted all of the rights and shall be subject to all of the duties applicable to the driver of a vehicle by this chapter
Which basically means a bicycle on the road cannot block 5 cars and remain on the road. Frankly, I'd pass law stating if there's no bicycle path or 3 feet of shoulder, it's illegal to operate a bicycle on that road and the punishment for violating that is a fine and the bicycle being impounded.
I say this as someone who as a kid biked EVERYWHERE. I DID ride on roads without a bike lane or shoulder but whenever a car came, I got the hell off the road to let them pass. I *NEVER* blocked traffic...which makes these spandex clad bicyclists all the more offensive to me.
