I think my car may have a loose vacuum hose. Whenever I'm at a stop with my foot on the brake pedal, the car vibrates. Then when I accelerate, it goes away. But sometimes there is no vibration at all. It's on off. If there is a loose hose, will it correct itself on it's own without adjusting it?
Play on the computer, drink your parents alcohol, go outside and cause mischief, skate, watch movies. I was 15 once, and was never bored.
Road humps? I'll assume for a moment you mean speed bumps. The reason for not placing speed bumps on a highway seems obvious to me but I will try to explain. Speed bumps are placed in areas of traffic where high speeds are not safe. Such as parking lots or densely populated areas. These bumps are designed to cause the driver of a vehicle to slow down. Out on an open highway the speeds are much greater than those of a parking lot or neighborhood. There are far less pedestrians out on a highway, therefor speeds are posted at higher rates. Speed bumps should not be driven over any faster than 3 to 5 mph. To do so would literally destroy the suspension system of most vehicles. Driving over a speed bump at highway speeds could blow out all of a vehicles tires and render the vehicle out of control. Very alert drivers who might see the speed bump would slow down to pass over it and this would cause a massive traffic jam, negating the very purpose of a highway to start with. So in short, there are no speed bumps on highways so that cars don't get destroyed and massive traffic jams aren't caused.
Depends on what that any means. Do you mean any as in if the electricity went out for 10 minutes or any as in a 10 mile diameter asteroid were to hit mid Atlantic?I can deal with most things that are likely to happen.
