Driverless Car Perspectives
Morning, Everyone. It's a great honor to speak to you today. My name is Olivia, major in Pattern Recognition and Intelligent System, mainly research driverless car. So, today, I'm here to tell you a little bit about how self-driving cars worked and the future of driverless cars.
Do you know that driving accidents are the no.1 cause of death? And do you realize that more than 90% of those are due to human error? Do you know that almost 200,000 people die on the roads in China each year, at a cost of over 1.5 billion dollars? Through driverless cars, we can avoid most of the car accident and regain the time we waste on the daily commute.
Now, I'll talk about how our self-driving car worked and what the future may become with these cars.
Firstly, let's talk about how our car sees the world. So, this is our vehicle, on the roof of the car, is a laser range finder, by which it magically can see everything around it. The rotating laser scanner like this, we called it 64-beam laser, can generate a detailed 3D map of the surrounding world instantly, accurate down to 2 centimeters. The car then combines the laser instruments with high-resolution maps of the world, producing different types of data models that allow it to drive itself while avoiding obstacles. Several computers inside the car's trunk perform split-second measurements and calculations, processing data from the sensors, and make decisions about every aspect of driving.
This image shows the 3d-data captured by the lidar. Our car managed 300,000 miles of testing autonomous travel without an accident, which far exceeded human driving. Our car has proven that the future is there, or at least, a short drive away. Now, the next question is what it will become if we release the car to decide which route to take?
Current navigation applications such as Google Map focus on optimizing for a single user - the driver - when crunching numbers to find the shortest or the fastest path. If the drivers are human, this is, of course, fine if they don't follow the apps' recommend. But once we replace the driver with the machines, they will definitely listen and follow the recommendations. If we can control all of the cars, then our navigation algorithm could optimize for the network flow, instead of a simple distance for a single driver, and will ease traffic jams, reduce speeding tickets and car accidents, waste less energy because of instead efficiency.
Soon, we may not be in the driver's seat, if the laser and computer take control, driverless car let us "just have fun" while the car does all the work. We no longer waste our time on the daily commute, we can do anything in the car, like dealing with official business, playing games or even having a lunch. Given how easily humans are distracted, someone died from a car-related accident every 15 minutes. We let software code take the wheel, some worry travel become so safety and so convenient.
After my presentation, I hope you can understand how driverless cars worked and the importance and the inexorable trend of the development of driverless cars. And here, is my reference. Thanks for your listening, and any questions, please?

Yuhua, your first paragraph is lacking first person pronouns which makes the way that you state your major, field of research, and and the purpose of your essay sound strange when read and spoken aloud. Your audience will know that your grammar is wrong. So in the first paragraph, insert the word I as in "I am majoring in... with a focus on the research of..." In order to fix the grammar presentation in that paragraph.
In the second paragraph, you have made incomplete statements. Driving is the No. 1 cause of death where? In the United States? Worldwide? Where did you get this information? Name your source. This is a research speech so the need for in-text citations in spoke form is still necessary. Phrase it for example, in this manner: "According to information from Google search, driving is the..." Make your hypothesis statement complete. What, in your opinion, makes driverless cars better ?
Third paragraph, first sentence, use present tense. You are discussing something that is still ongoing. Don't say " how our car..." since you are referring to a concept car. The correct term would be "The concept of the driverless car works based upon an intricate system composed of..." Change all the references from "our car" to "the concept car" as that is what a driverless car is at the moment, a concept car.
Paragraph 6 and 7 requires the most corrections. Let me just rewrite the paragraphs for you:
Once the laser and onboard computer takes control of the driverless car, we can finally "just have fun" while the car drives to our destination. Allowing us free time to deal with other important things in life like catching up on paperwork, relaxing, or eating during the ride to work. Humans will no longer be distracted while driving, thus reducing the amount of car-related accidents, which seem to occur every 15 minutes these days. When software code takes control of the wheel, driving becomes safer and more convenient.
I hope that you now understand how driverless cars work and why it is an important technology that needs to be developed if we are to make our cars and roads safer for all concerned. Thank you for listening. I will now take questions.
Thank you for correcting me!!! You really do me a favor!! I especially appreciate the information and advice you have provided. Your assistance has been invaluable to me during this process. Again, thank you so much. I greatly appreciate your generosity.
I rewrite the passage on your suggestion:
Morning, Everyone. I'm Olivia Zhu, I am majoring in Pattern Recognition and Intelligent System with a focus on the research of driverless cars. So, today, I'm here to tell you a little bit about the present status and the future of driverless cars.
Do you know that driving accidents are the no.1 cause of death in China? And do you realize that more than 90% of those are due to human error? According to the information from the World Health Organization, more than 200,000 people die on the roads in China each year, at a cost of over 1.5 billion dollars. Now I think there's a new technology here - driverless cars. With driverless cars, we can avoid most of the human error, thus reduce the car accidents, even regain the time we waste on daily commute.
Now, I'll talk about driverless cars mainly on three parts: how self-driving cars worked, the present status of driverless cars and what the future may become with these cars.
Firstly, let's talk about how driverless cars sees the world. As you can see, this is our vehicle, on the roof of the car, is a laser range finder, by which it magically can see everything around it. The rotating laser scanner like this, we called it 64-beam laser, can generate a detailed 3D map of the surrounding world instantly, accurate down to 2 centimeters. The car then combines the laser instruments with high-resolution maps of the world, producing different types of data models that allow it to drive itself while avoiding obstacles. And several computers inside the car's trunk perform split-second measurements and calculations, processing data from the sensors, and make decisions about every aspect of driving.

Yuhua, you are still having a slight problem with your tense usage at this point. It is not as bad as the previous version of the essay but it still causes stress for the reader as you still go from present to past tense while talking. Let me point out the correction for you:
...how self-driving cars WORK - This is in current time so use present tense
... future may BE with...
... how driverless cars SEE the...
... , which far EXCEEDS human driving ABILITIES...
... proven that the future is HERE...
Now, the next question BECOMES will DRIVING BE LIKE if we ALLOW the car ...
If the drivers are human, THEN IT IS ALRIGHT EVEN IF THEY DO NOT FOLLOW THE APP'S RECOMMENDATION...
... algorithm could BE OPTIMIZED ...
... less energy because of
... , we have considered how self-driving cars WORK...
The next time you write your speech, take note of the grammar mistakes that you made in this previous essay. Most of these mistakes could have been avoided if you just proof read your speech prior to delivery. That is the most essential part of the proof reading work of any paper.
