I can understand people using a large vehicle if they need it for work, but there are no excuses for using one for recreation. It is selfish, and I'm glad to see social
um this isn't entirely correct. A bigger vehicle these days aren't always less efficient than a smaller vehicle.
There is a trend going on right now. SUV mileage is going up because people have started buying less of them. Meanwhile middle segment of cars are actually going through "horsepower wars" and MPG of these cars have actually fallen. You can find plenty of crossovers that do 20-30mpg. Meanwhile, if you look about what's going on among BMW/Merc/Acura/Audi/Lexus/Infiniti. It's all about horsepower. Common average use cars like 335i,G37,IS350 are pushing towards the 270-300hp range. Most people don't "need" this. They are burning more gas than your Acura CUV,Ford Edge's, or BMW X5 six banger. You want to regulate them too?
BTW toyota makes hybrids, not because they really care about the environment by itself. They do it so they can sell more cars that have more V8's and aren't as environmentally friendly. Car manufacturers have to abide to CAFE emission rules, and there's some metric that says X percentage of cars have to produce Y emissions or below, and on average vehicles from a manufacturer meet some criteria. Toyota needs to sell these prius to enable them to produce more lexuses, camry, avalons, 4runners,sequoias, and tacomas/tundras, that guz gas with the 300+ hp v8's. So while your intentions might be good to "save the environment by buying a prius", behind the scene you are actually also enabling toyota to produce more less-eco-friendly vehicles for others to buy.
Honda on the other hand doens't have an V8 offering in any of their cars. Honda arguably is more green than other cars. BUT they are getting killed in the american car markets, because they're cars are felt as no longer competitive offerings.
American consumers demand higher performance these in recent times. They haven't till now considered mileage as a purchasing decision until now. The price of fas is simply responding to demand. This is a free economy, when the price of gas reaches to $5+, it will sort out who really can operate 300hp machines of any kind and who cant.
