But you are completely overlooking the factor of throughput, or speed of the vehicles.At highway speeds, the majority of running lane space is not taken up by a vehicle's length. It is taken up by the gap needed between vehicles to ensure a safe following distance, otherwise know as the two-second rule. At 100 kmph, that distance works out to be 55.6 meters give or take a few centimeters.
That distance is the same whether for bike or for car or truck. The length of a vehicle, whether is be 2 meters for a bike or 6 meters for a truck, is only a small fraction of that. If you want to save real estate on a highway, the most effective way is to reduce the number of vehicles, which in turn reduces the number of safe following distance gaps that use up most of the space on our highways when they are free-flowing.
That two second gap is only 55m if you are doing 100kph.
By your reasoning, we should just lower the speed limit to 5kph, so that everyone could safely drive bumper to bumper.
As far as fuel consumption, there is no point comparing the mgp of any vehicle measured at a constant 100kph when it is going to be constantly moving from 10kph to 100kph to dead stop to 50kph all the way allong it's trip. I'm sure that simply by virtue of the lighter total weight (or even weight per passenger, if you prefer) that bikes burn way less fuel in the stop/go gridlock that the HOV lanes are there to alleviate.
What really matters is how many people you can move past a certain point in what amount of time.
Bikes cut through traffic faster, and burn less fuel doing so.
No manipulation of numbers is going to change that self-evident fact.
Personally I think green cars should be allowed and so should bikes.
Both reduce emmissions compared to the average commuter's cage, and I maintain that pollution control is the primary motivation behind the goal of reducing congestion.
