Where does the money to build and maintain roads come from? Oh yea, road use tax in gasoline, parking meters (do bikes have to pay to park?), drivers license, vehicle registration? Oh, and keep up with pace of traffic.

When bikes start paying road use tax by the mile, require registration, inspection.. then maybe you have a legit reason to complain. In the meantime STFU.

Venus ~96.5% Carbon dioxide
Earth 0.038% Carbon dioxide

Wow yer right we are on our way!

We only have to increase the CO2 levels by 2539 times and we'll be there!

I just can't help but think of those poor starving plants.. only 0.038% of the atmosphere is suitable for them. Meanwhile 20.95% is oxygen for us. That's why I like to burn fossil fuels. Think of the trees!

yes, and I would be pissed if the government said "the only source of meat will now be tuna", I don't eat it.

It already is, goto a public library and access the WWW.

"This way criminal can be hunted down by any means necessary while still giving honest people some means to keep the police in check."

Innocent until proven guilty, what you are suggesting allows them to 'hunt down' innocent people who are suspected of being criminals. Not to imply police are un-intelligent, but if police officers were able to determine if you are a criminal in advance, and reliably, then we would have no need for courts.

Mass of the batteries. It takes significantly more energy to have an effect on a 50,000 lb truck than it does a prius. All highways have weight restrictions (its based on axle weight), thats why they have weigh stations. Its very common to be traveling only 100 lbs under the weight limit. Sometimes drivers cannot fill up their fuel tanks or risk being over weight. If the federal government allowed higher weights for batteries you might see some effect.

Little Note: Most tractor trailer engines require 3 or more large batteries to start. If left to sit in a cold temp like 20 degrees F, some do not start at all. You are talking about a much larger engine, and a much greater mass.

Another note: most cars have 3-5 speed transmission, most trucks have 10-16 speed transmission, which enables more efficiency options.

New trucks with all the "anti pollution" crap get 6-7 mpg with 50k lbs.. Do the math on a prius and compare. (get rid of the "anti pollution" and they would get 10+)

If you aren't creating wealth in some form or another for the society you are living in you are leaching off of it. Ant colonies don't support lazy ants, everyone has a role. Only in the human species do we support others of our species who contribute nothing. There are many ways to contribute without working a traditional job, sharing experience, mentoring, and just being a good example. I don't think sitting at home watching Oprah qualifies.
