What the heck does that have to with a government making rules against it?
Governments make ineffective (even backfiring) stupid laws all the time.
(heard of utility deregulation in CAL ?)
What you don't know is this is actually a backdoor attempt in particular sponsored by the Sierra Club to close as much public land to any useage by the public as they can... Particularly off-road vehicles of any type (including bicycles in many cases).
They threw in street legal bikes to make it look more legitimate.
Instead using specifically banning the target vehicles from target land... they figured they could make emissions levels so stringent that almost no vehicles can pass them.. and thereby accomplish their goals.
And if you are considering if these rules would be "fair".... Consider this..
Large trucks, buses, all airplanes, and all boats have NO emissions limits.
And a motorcycle in general put out a LOT less pollution than your average large truck, or large airplane, or large boat.. Wouldn't you agree?
Now consider how many motorcycles you saw today...1?
Now consider how many large trucks you saw today...200?
Now say a large truck puts out 25 times the pollution as a bike.
200 x 25 = 5000 times as much pollution from large trucks than motorcycles (& peds).
Hmmmmmm... And yet the Government wants to put more restrictions on bikes?
Hmmmm... Do you get the feeling that the gov is trying to stab us in the back for some reason?
E-mail your favorite unrepresentative jackass and tell him (them) you don't want it.
It's supposed to be government for the people... Not government for special interest and lobbyists.
