I had planned an article detailing why hybrid cars, in the long-term, are pointless. However, OmniNerd have already done a good mathematical analysis on the economic viability of hybrids, and finds that unless you do many miles they’re not.
You might then argue that hybrid cars are better for the enviroment, and you’d be right. But there are many more effective ways of reducing your energy usage and being “greener”. However, that discussion is for another article!
