And in the mean time, they can stay in business. Interesting fact: At one time in automobile history, there were more electric cars on the road than gas powered automobiles.

That last part - my professor pointed that out. She said had we spent 80 years developing electric motors, we'd have really awesome electric cars today. But we developed gasoline, which wasn't a terrible choice given the technology at the time, but as a result we have really awesome gasoline engines.
The key to electric is finding a power source for charging the cars. If we are using fossil fuels to generate electricity to power cars, we'd do better just keeping the gasoline cars. But if we can use solar and wind to charge our cars, it could work.
Anyway - her point was valid: We need to study alternatives because someday we will not have enough oil. But we can't compare petrol's bad attributes to an alternative's good attributes. It's not a fair comparison. But we should compare the good and bad of each fuel to the good and bad of the alternative.
As a result, gasoline is actually quite good. Most emissions are only CO2 now, which is good news at least as far as human health goes. Other alternatives may have less carbon emissions, but may emit other gasses that may be bad for people.
But gasoline has an iffy future. There are carbon-emission issues. So, we can't just keep doing what we're doing.
