First, Brazil's economy is one-tenth the size of ours, and Brazil's motor fleet is about 100 vehicles per 1,000 people. Brazil's cars and trucks consume about 15 billion gallons of motor fuels annually....
In contrast, there are 765 vehicles per 1000 people in the U.S. consuming about 150 billion gallons of gasoline per year.
Pure BS, gas mileage rates would take years to adjust, and cars are not going to get better in a big way until some technology breakthrough, and that isn't likely either since physics dictates fuel economy.
Big rig mileage isn't going to get better until trucks are able to triple trailer or carry more in a single trailer. Those things are dependent on roads ability to carry the loads.
Ban cars and trucks and go to bikes mopeds and scooters, and kill the economy, or drill for what the media calls fossil fuels, another grand lie in the scheme of things.
The oil from dinasours/fossils myth is as mythical as the earth being flat, which among ancient explorers, was also a myth.
Oil is the fuel of choice and will remain so for years until another item is discovered if ever, that will replace oil given another fifty years or so to develop as oil has.
Drill for what ails us is the solution, and support the drilling by building refinaries to handle the increaded production. Build latest generation nuclear reactors for power generation, and work out the nuclear waste problems.
Meanwhile supporting with enabling legislation every worthwhile energy efficient discovery, and energy saving technology. We start from right where we are now.
Rather than increasing government regulation, just let the market handle it. $3+ gasoline is a big disincentive for using a gas-guzzler for long-distance commutes
On the flip side, my wife drives a van. It's big, it makes it possible to transport several kids, their friends, and a lot of gear, and is otherwise very useful. It's a gas guzzler, but she only drives it about 60 miles per week so it doesn't matter
