With this ticket I have learned that it is not okay to speed. You should always pay attention while driving no matter how experienced you are. You never know what could happen. There is no need to travel at a faster speed than the one that is set by the law. I have learned that you don’t need to rush to get places. You will get there eventually. I don’t need to be in such a hurry going places. Speeding does not help you get anywhere faster. All speeding does is increase your chances of injuries

reduce engine noise emission. If you have ever heard a car running without a muffler you will have an appreciation for the significant difference in noise level a muffler can make. If vehicles did not have a muffler there would be an unbearable amount of engine exhaust noise in our environment. Noise is defined as unwanted sound. The down side to reactive mufflers is that larger backpressures are created‚ however for passenger cars where noise emission and passenger comfort are highly valued

A driverless car also known as a self-driving car is an autonomous car that can sense its environment and navigate itself without any human intervention. No autonomous car relies on a single sensor because it wouldn’t be accurate. A perfect example of this is the Google’s self-driving car‚ it does not only rely on GPS data because it wouldn’t be accurate enough to keep the car on the road‚ let alone in the correct lane. Instead it uses eight different sensors to keep the individuals inside and the

Electric Cars vs Gasoline Powered Cars Electricity. One word that can rescue the earth from its current demise‚ global warming. Since 1880‚ global warming has increased by 0.8° celsius which may not seem like a substantial increase but it is. According to (NASA 2014) the average weather changes everyday in different countries‚ but this is the entire world’s average temperature. A 1° global change is significant because it takes a colossal amount of heat to warm all the oceans‚ atmosphere‚ and land

Gasoline Verses Electric Vehicles A wave of environmental values and a reduction in production costs is causing many consumers to consider trading in their gas powered cars for an electric counterpart. While the shift from gas powered vehicles to electric is still relatively young‚ recent changes have caused it to pick up significant speed. When comparing the advantages and disadvantages of gas and electric vehicles several options should be considered. A few of these options are overall cost‚ flexibility

Hybrid cars are better than traditional cars because they are environmentally safe. Sandra Ariskan explains that “Hybrid car will generate much less gasoline combustion and emission of CO2 is therefore significantly minimized ” (Hybrid Car‚ an Effort to Safe the Planet par. 4). Basically Sandra Ariskan is saying that by minimizing the CO2 from the air than your protecting everything that is going extinct and safer for everyone and for the future. This means that the engine that comes with a hybrid
