It then requires a system that can regularly download the data, bearing in mind that there is no mobile phone coverage in most of the area of the country, and many car owners have no internet access. Having agreed on a common system between all the states and territories for such a system, and enforced compliance, there is merely the problem of ensuring that the data base and individual devices cannot be tampered with or hacked, and is free of significant bugs. 
I won't say it is impossible, but I wouldn't hold my breath waiting for it either.
