CHECK GRAMMAR...PLZ

As time progresses, people are continuing to develop new technology and devices for people to use. {They [這個they有點confusing，按文法是前面的subject=people，但明顯你是指technology(單數)和devices(眾數)加埋的they] make life easier.}[可以改為These developments make life easier. I think the motor vehicle is a good example of this. There are many types of vehicle,such as buses, cabs[的士不是機動車種-是一種出租的car], cars, trains. I think the car is the best in all vehicles. There are three things that prove my thesis [thesis這字的意思是主題，你想說的是命題或立論?英語人會用my argument作為你立論跟人討論的用詞] is correct. Firstly, I can drive my car everywhere that I like. Secondly, I regard sitting in my own car as more comfortable than sitting in a public vehicle. Lastly, I believe that public transport fees are more expensive than the gasoline cost. Let me explain them one by one.First of all, I can drive my car everywhere that I like. As public transport cannot take me to everywhere, it is very inconvenient for me. People may say that I can take a taxi, but it is very expensive for me to do so. If I take a taxi, I need to pay about $20 for one-way. Moreover, when I feel bored at midnight, I can take a joyride. There will not be any public transport services at midnight. Therefore, I believe a private car is the best.Secondly, I regard sitting in my own car as more comfortable and safe than sitting in public transportation. The seat of my car is wider than public transport seating. There are excellent safety equipment in my car.[後面展示多於一種] For example, there are seat belts in my car, a safety inflatable cushion that prevents my head getting hurt in an accident. On the other hand, there are no seat belts on the bus. The seats on the bus are very tight. I do not have enough space to move. Therefore, I believe a private car is the best.

.[如果你是論證便要提出實質數據-如果你自駕車同樣的距離和路程要多少汽油費-我相信如果每天出入兩次你也開車公共車費$5.1(不知你是否用學童優惠價來算)但假如你是自駕便不可用這特惠價來比較了。我相信走$2.5一程車費坐某些公共交通大約可以走5公里距左右吧(大約三個mtr站)，用汽油計可能也要$5以上一程吧(大約$1/km)，未計算你的停車費和車價攤分計作每天支出]

are you going shoo????
