Yes, we’ve heard it again and again, seatbelts save lives and this is true if they are indeed used. There are however some precautions in the use and care of seatbelts which like any other part of your car is a simple machine that can indeed mean the difference between life and death in a crash. Now to begin with, statistics show that most injuries occur at slower speeds (too high the speed and even seatbelts cannot provide total safety without supplementary support from airbags and other active systems) and in the most unlikely places such as the parking lot where say the car backing up behind you miscalculates and hits you injuring your neck or smashing your face onto the dash or steering wheel. So even if you do not expect to go far and fast, just wear it so you are protected from such incidents.
If you do get into a crash while you were wearing your seatbelt (May it be at slow or fast speeds) have the seatbelts inspected (by a certified mechanic of course) for any damage. Since the belt itself retracts into the side of the car’s decorative moldings, there are several parts that need inspection after such an incident to assure you stay protected in the event of another crash. The restraining action of a seatbelt (which many of us hate for it wrinkles our clothes and causes streaks across your new white shirt) is done on purpose to prevent your body from getting thrown around in the event of a crash. It holds you against the seat (which is usually contoured against your body) providing maximum protection from a rear or frontal collision. Seatbelts can be quite effective in a frontal or rear collision, but with side impacts, not as effective without side collision airbags, reinforced doors and other supplemental restraint systems in most high end cars. The amount of material and space between you and the door is so small that yes you can be protected from a little force but at higher speeds, seatbelts may not be enough.
Ending this, these safety belts should be worn properly (which is stated on your owners manual) the lap belt on your hips or belt line and the shoulder strap across your torso. Placing it in other places defeats their restraining properties thus rendering them useless in the event of a crash. If you have children, adult seatbelts are not suited for them for they can easily slip through adult sized belts, consider getting child restraint systems such as a child seat or adapters that lowers the points at which the shoulder belt is in relation to the torso. Children are always safer at the rear rather than in front even with safety equipment. Also take into consideration that even the most expensive child restraint system if not properly installed would result in no protection at all for your child. Buckle-up for safety’s sake, for the life you save can be your own.

Well, this might have to do more with the way the human body is designed and how much information we can process in a short period of time. Scientific data has shown that our actual active line of sight window (or the area of our vision which is fully analyzed and can be reacted to instantaneously) is limited to a few square inches in front of you. The rest is what is considered to be the peripheral vision area which we are aware of but do not have too much concentration on. Add to it the tunes playing on the radio, the shifting combination of the depressing the clutch and changing gears and you have a lot of information to handle for the human body to actually process (try this test to see if you are a safe distance from the car in front of you).
At 40 kmh, the average car (with stock brakes) can stop reliably in about 5 car lengths which translates to around 50 or 60 feet. This might sound quite far but this is true. Now back to the speed limit thingy, well these are placed due to many considerations such as the type of road surface, the amount of traffic that is to be expected, and the surmised fuel savings and so on and so forth. The one about speed in relation to fuel consumption is a good one, for at 80 kmh, your vehicle is running in balance with it’s weight and the momentum or it’s forward thrust that the engine is running efficiently burning only enough fuel to maintain that speed no more and no less. Now with most carburetor type vehicles that would be a good idea for these vehicles do not have computer brains like the newer models of cars which seem to have technology crammed into each and every corner.
The ECU (Electronic Control Unit) or computer of newer cars has the necessary programming to obtain information from a bank of sensors on the engine (temperature, idling speed, revolutions, amount of air entering the engine and many more) that allows it to adjust the performance of its parts to provide or attain maximum efficiency while maintaining fuel economy. Depressing the gas pedal on a carb-type vehicle and you pour gas into the engine even if it doesn’t need it sending some into the overflow line onto the street. Newer cars have recovery lines which send excess fuel back into the fuel delivery system or the gas tank for re-use. The speed limit is the determined safe speed to maintain necessary distances for braking allowing you enough time to react properly to the events that unfold such as in emergency cases in front of you. The human body reacts quite fast (in milliseconds actually which is the time your eyes see the information, sends it to the brain, processes it and comes up with the necessary response and sends the nerve impulses to the necessary muscles on your limbs for you to react) but at high speeds, that might not be enough. Why race down a street which is only a few blocks long? Just ease on the gas pedal and accelerate gradually for it not only saves fuel, it also saves on the wear and tear on other parts of the vehicle(brakes, suspension and other parts). Enjoy the trip and not the ride for it allows you to ponder about better things than the darned traffic jam ahead of you.
There have been recent studies that have shown that Nitrogen gas for use in inflating your car’s tires makes them last longer. Well, there might be a good scientific backing for this for many of the new muscle cars that are coming out onto the market have them in their tires. Nitrogen being an inert gas that prevents the problems associated with regular compressed air which contains a sizeable amount of moisture that causes corrosion in aluminum and steel wheel rims. Oxygen causes oxidation which can eventually weaken wheels whatever type they may be. Nitrogen is also cooler than regular air which can translate to better mileage which may be needed due to ever increasing gas prices. As it turns out, the tires on your car looses air even if it does not have a puncture which translates to 2 psi per month compared to 6 months for nitrogen gas.
Nitrogen also causes less problems with your car’s wheel valves making them last a tad longer than usual. Wheel valves should be replaced everytime you have your tire changed to ensure they are at par with the wheel. They might be slowly leaking air which if added to the leak in the rubber tire can get you in an odd spot when you least expect it. Also, it would be a good idea to make it a ritual to have the tire pressure checked everytime you fill up to ensure your wheels are running as designed. Uneven wear, cupping and other wheel maladies should be taken seriously for they are indicative signs of other problems such as in the suspension. Low tire pressure leads to poor mileage (it also heats up the wheels excessively even causing failure). If you have experienced having to run on a flat tire due to an emergency or unexpected flat the tire would surely be a goner for the plies of the tire tends to separate on the sidewalls for they are not designed to come in contact with the surface of the road. Till next time, keep safe on the road and off guys. Drive safely.
