There's going to reach a point where fuel's prices and exclusivity will hit the zenith, and if it ever happens to be replaced by a far more efficient and eco-friendly alternative that is able to see mass production on a level similar to gasoline, then there will be nothing left to do but to squeeze as much power and grunt out of that new alternative fuel as possible, like a lemon in a juicer. It'll be just like what was done with gasoline at the top of its game in the 60's and 70's. Once the cost and exclusivity puzzle is solved, mankind's lust for power and speed will take over.
That is what I'm patiently waiting for. :P
Electric cars, as an example, are pricey and exclusive if you want to get into performance such as a Tesla roadster, but once electric cars become more standardized, the technology will improve to a point where it will usher in a glorious repeat of the muscle car age where manufacturers, untethered by emissions or fuel economy standards, are free to make their sale over which has more horsepower. As for the sound... well, you win some you lose some but I'm sure they'll figure something out. Suffice to say, that's a long time down the line and most of us will probably be dead before it comes to fruition, but it'll eventually happen. Most people work their best under pressure, as sad as it sounds, and when gasoline's price gets so far out of hand that the day-to-day economy is ruptured, people will act.
Until then, I'll drive my gas-guzzling V8 (which really isn't THAT bad on gas) so we can reach that point all the sooner.
