If you look at NASCAR history, in the 60's the automakers knew there was a limit to how much horsepower you could create to go fast. They turned their attention to aerodynamics - which is why Chrysler came up with the Superbird. Windtunnel testing is commonplace today.

Necessity is the mother of invention and as we drive to reduce gas consumption, emissions and make cars safer, you can only get so much from weight reduction and engine performance. Admittedly, there have been great strides in engine design and fuel economy but there are limits. We are at the beginning of that.

The other thing that is happening - there are fewer 18 yr olds driving today than at any time. Car loan terms are longer. The desire to own a car, especially in urban areas is almost a liability. That $30K cars sits more than it is used. Its no wonder why ride share is popular.

As long as gas prices remain low, it may slow the proliferation of alternative powered vehicles but it won't slow down ride share.
