If there was a theme at this year's Paris motor show, it was: Show me the plug.
Electric vehicles of all sorts seemed to take over the show. It was almost as if you wouldn't be allowed to exhibit unless you were showing off some sort of electric vehicle.
I'm not sure when -- if ever -- all those vehicles are going to hit the market. But if they do, you might get the idea that they're flooding the market.
I don't understand the rush to electricity. No one argues that there isn't a place for electric vehicles, both plug-in hybrids and pure electrics. But the potential market share for electrics is very small.
About the only explanation for all this interest in electric vehicles is that it seems to be politically driven around the world.
If each of those companies went into production with an electric vehicle in the next couple of years, we would probably have the world's biggest short circuit.
After Toyota's success with the Prius gasoline-electric hybrid, it will be interesting to see whether the Nissan Leaf electric vehicle will be as popular.
"Range anxiety" isn't likely to have a great deal of influence on consumers' buying habits because the limited range of electric vehicles will mean they appeal mostly to urban consumers or folks in America who see them as a second or third vehicle in their household. Time will tell.
But we all had better get used to seeing lots of plug-in vehicles introduced in the next several years.
Obviously, the experience of the first owners will have a huge impact on the success of electric vehicles.
If the early experiences are good for the owners of plug-in vehicles -- as well as the experience of customers at Enterprise Rent-a-Car -- manufacturers who took a gamble on those vehicles may have a great success on their hands.
But if "range anxiety" is real, a lot of manufacturers very quickly will pull the plug on their plans for electric vehicles.
