Hoon's car crushed by police to send message to dangerous drivers

An Adelaide hoon jailed for driving 143km/h over the speed limit has had his beloved Holden Commodore crushed as the state government sends a message to other dangerous drivers.

Tarelle Power Williams was the first South Australian to be jailed after he drove at 253km/h in a 110km/h zone while on his Learners licence earlier this year.

The 20-year-old was sentenced to a year behind bars in July under the state's new tough hoon driving laws.
