I have to produce a report on this for my science coursework and am a little stuck.. :S
some of the questions i need to look into are:

1) give reasons why there have been changes to speed limits for cars in Great Britain during the last hundred years

2) Who designed the first speed camera. Describe how one named type of fixed speed camera works.

3) How does the air bag work? How do air bags reduce injury?

4) Compare the features of a modern car with a very early car. Apart from air bags, describe TWO DIFFERENT safety features that are used in modern cars to reduce the risk of injury. Use ideas about speed, forces and energy to explain how these features make the car safer.

Would appreciate if you could help answer any of these questions in as much detail as you can. Thank you =]

Out of all the luxury cars, which car is the most expensive to maintain and repair?
I was just wondering because I currently own a ‘98 Mercedes C230, and I’m trying to figure out if I should keep it or buy something else. BUT I need to know if it would be the best option because I might be putting more money into a newer car (any) , but I do want another luxury-type car. Any suggestions?
