Is there a potential problem behind every HYBRID car?

There's so much hype about this vehicles its amazing. Don't get me wrong I'm for the environment, but car companies making this vehicles have a major task and that is to make them safer...what? Yes, safer for the people driving them.I read an article sometime ago talking about concerns of what would happen in a major car accident involving a hybrid vehicle. The article talks about potential electrocution not only on occupants

but imagine that a person or even emergency personnel is trying to assist you, they might run a chance of getting themselves in a bad situation. Car companies are reacting fast to these concerns by saying that this cars are 100% safe and there's no chance in a scenario like this for potential electrocution happening at all. Another situation is the cost of maintenance on this cars. For example; Batteries on this vehicles are expensive costing between $5,000 & $8,000 dollars and the life of these batteries are about 6 to 8 years. So what's going to happen when you have your $27,000 Toyota Prius paid off after 5 years and all of the sudden you need to replace the battery on it . The problem is that your $27,000 Prius depreciated a lot during the past years and now its probably worth maybe $8,000 dollars and you have to come up with 6 or 8 grand to buy a battery pronto. Now what happen with all that MONEY you save at the gas pump all these years? You ended up spending it on your car again buying the battery your car need and the fact that your car its worth less MONEY than the battery your buying for it makes the argument of putting MONEY in your pocket by buying less gas worthless .We know now that the more these cars sell the prices on the batteries would go down ,but my real opinion on this cars is that to me they are just a statement to the people who drive them saying... look at me I'm more environmentally friendly than you ,GO GREEN OR DIE MEAN just look at the Hollywood people driving this things all over the road on BEVERLY HILLS BLVD they are saying to the masses to be friendly to the environment but when they are filming a movie or traveling on a trip they jump on big planes burning all that jet fuel into the atmosphere...So what's the point? You be the judge. For now I just hope they can lower the price on this batteries as they continue to sell more of this vehicles because with gas prices going up everyday and the situation in the middle east going worse by the minute we all might consider a hybrid car in the near future too.
