the practise test 3-My

In the lecture, the professor talks that there are some problems with the speed cameras. He indicates that the reading are not convincing when compare with what happened in real.

Firstly, the professor brings the idea that speed cameras cannot guarantee the divers will slow down their speed. This casts doubt on the claim in the reading that driver will drive carefully in a safety speed. There is no evidence to prove that driver will travel in safer speed. People go fast as usual and only suddenly decrease the speed when seeing the speed cameras or police officials. That also put cars around in dangerous in such cases.

Furthermore, the reading says that the camera speed can reduce part of the police office duties. However, the professor contradicts that machine cannot do mission as the police officers do. Machine cannot deal with the dangerous violent actions such as controlling people who drink alcohol and bring gun and cannot judge guilty people.

Finally, the professor refutes about the evidence which speed cameras can record. He argues that speed cameras are machines which can be error without the dictation of people. Consequently, they will show wrong data. Therefore, people cannot absolutely believe in this kind of machine.
