What kind of additives are you guys talking about? I'm curious too, I'd love to be able to economize more, wherever I can. I already stopped taking the car to the car wash, I just wash it myself most of the time. Whatever helps to reduce monthly costs.
I took my road test in a very big car, it was very uncomfortable but it was the one I learned how to drive on. Afterwards, with the license in your pocket, you can practice driving on whatever you want.
My first car had one, you could unlock it with the car keys only but now that I have another car, well.. I just have to be careful. Maybe you could have it custom made, it will cost you but in the end it's worth the trouble.
I remember seeing a movie a very long time ago. I can't remember what movie it was but what I do remember is a lady constantly telling the driver to drive slow because this will save gas. Is this true? Does driving slower help you save gas?
While I was in driving school they taught us not to listen to music too loud because you need to hear the traffic and sirens or any other important noises, but they never said how loud is too loud. What do you think? How loud should you set your speakers?
