Scott Adams of the Dilbert comic strip has a great blog where he often shares very insightful ideas. Here's an excerpt from a recent post.
And this got me thinking about why we have so many cars in the first place. Excess cars cause traffic, pollution, and dependence on foreign sources of oil. And who benefits most by this situation? Answer: car makers.
Suppose the government enacted laws that made it legal for anyone to be a taxi driver in his own car without a special taxi license. And suppose the income was non-taxable. The result would be cheap taxis and high availability. Every time you wanted to run an errand, and had an extra minute, you could choose to pick up a rider and cut your own driving expense in half. Technology will make it easy to match amateur taxi drivers with riders. And the market would keep prices low.
Now obviously there are lots of problems with this scheme, in terms of security, liability, and people puking in the back of your Hyundai. But compare that to our current problems: car expenses, traffic, pollution, global warming, and excess energy use. I think the universal taxi scheme comes out ahead.
