Exposition - should year 2 children be able to seat in the front seat of a car?

I believe that year 2 children should not be allowed to sit in the front seat.

Firstly, the airbag in the front seat may hurt them. Secondly, you will have a chance of getting knocked out in an accident. Finally, you could have an argument.

Year 2 children should not be able to sit in the front seat because it is not safe.
