It's worse on country roads. Alot of blind hills, driveways curves etc. I've had several of these annoying cyclists pull out in front of me, not obeying traffic laws, swerving cause there bullshiting w another wannabe lance Armstrong etc etc. They're a hazard to other motorists.
And I agree with making them be licensed, wanna ride your huffy on the road get a plate and registration like everyone else.
No business on the road period. That's why were have things called bike paths and trails in parks. Roads are for motor vehicles.
