I think the problem is that riding a bicycle on motor vehicle road is an inconsiderate act.
Its not wrong...its just inconsiderate.
Like paying at the express lane with a bag of pennies.
The first motor vehicle drivers were inconsiderate.
People pulling gigantic rvs are inconsiderate.
When I take the highway with machinery instead of a much longer dirt road...I am being inconsiderate.
It happens.
Bicyclists seem less remorseful however!
