Tanking ecomomy? We just bought a car. What now?

My parents are amazing. They are super stingy with money most of the time but then sometimes they just spend large amounts of money in one shot. That's right. No lease. No financing plan. Just pay the money straight up. I guess in an Asian kind of way, this is logical since you have to pay less money total if you consider interest. Anyway, the new car is a Toyota Venza. I wanted them to get a hybrid but they said that we didn't have a car that could fit 5 people. The Venza has five seats, same as the cars we have now. Well, I will admit that it is much spacier(if that is a word). The car is pretty nice though with all these high tech gadgets and stuff. It also looked pretty safe with all the airbags that could pop up from all over the place. I have a question though. Why don't they have any airbag type things on the outside of the car? I guess it would be kind of late because another car would have already hit the outside of the car for it to deploy. But most crashes don't just involve one collision so if air bag thing deployed after the first impact, the second and later impacts would be damped significantly. Also, if you happened to crash into water, this would keep the car afloat. Just a quirky idea. If you happen to take it and make millions, I expect your first child in return. Think about it.
