I'm writting my personal statement at the moment with a view of doing mechanical or automotive engineering at uni. I've read various articles that say giving an example of a problem is good, it gives you something to talk about in an interview and it gets the reader interested.
One issue i know of with current cars is they're very inefficient, weight obviously has a role in this. Sidelights were introduced on old cars as the batteries weren't upto the job of running proper headlights but current batteries can cope with this. And, when i was learning to drive my instructor told me to always use headlights rather than sidelights.
So, why is it that current cars have sidelights? Are they required to make the car road legal? I don't want to write something and look like a total tit because it's a legal requirement.
Thanks
