Hi, Justin.

I was not suggesting Culway's data is accurate enough to be the basis for
prosecutions.

It is designed for providing intelligence to state road authorities so, in
part, they can pinpoint where and when they should focus their more labour
intensive enforcement measures.

That is why I said it is slightly peripheral to Mr Roux's request.

But, as a technology, it could help Mr Roux's efforts to effectively deploy
portable scales in South Africa, and he might be unfamiliar with Culway.

Cheers,

Bob Murphy
