I agree with the comments regarding more driver training. There should be something similar to what they have in the USA. Also I do think that younger drivers should have some limits on 1. Who can be in the car with them and what times. 2. Power limitations to cars. 3. Maybe some sort of speed limitation device so that the vehicle won't go over 100km/h.
I never used to think that these things needed to be done ( or something ) to help lesson deaths on the road, nor really thought it could happen to me. I have a daughter and seeing this article on the weekend was a bit of a eye opener.
