I have found that a persons level of environmental concern
depends on where they live a lot. I grew up in Michigan,
which is mostly flat, and has a low population. Polution
just blows away. There is very little environmental concern.
Most people drive gas guzzling vehicles and a lot of people
just burn their trash and heat their house with wood. I
remember one of my friends who is into high powered vehicles
saying that you could just bash all of the stuff in a catalytic
converter out for better exhaust flow. He would just put a
piece of pipe on there if a catalytic converter wasn't required
by law. They don't check to make sure that the catalytic converter
is actually working though. He just rebuilt the engine in his
truck with a bunch of aftermarket parts. It is a 390 (old, very
large engine; used to be used in busses and such, I believe).
He spent about $4000. He used an expensive aluminum head,
aftermarket crank shaft, headers, aftermarket carburator, and
various other parts. He was planning on driving it to work
every day, about 32 miles there and back. It requires premium
gas, and it may get 5 miles to the gallon or so, I don't really
know. It would definately be under 10 miles to the gallon.
Hopefully he has reconsidered with the higher gas prices.
