This is based on the drivers own statement, we weren't there, we don't know. This was not a D.U.I. and there is no mention of mobile phone use etc. The unfortunate reality is, that these kinds of accidents happen on a daily basis. If there was a prior record of malicious intent the punishment would be more severe.

The dangers of motor vehicles were well known several decades ago, yet nothing has changed, that doesn't happen by accident.

This holier than thou attitude isn't going to solve anything.
