The Chinese copies have to be worth a punt at the price.
I've been caught out more than once by the Sydney tolls. Once driving a hire car back to the airport I missed a turn on the highway, I turned back at the first junction and got charged two toll charges, one in each direction, that I didn't need. Another time I managed to be in the wrong lane crossing the harbour bridge, didn't realise until the lights lit up and the sirens went off. Got chased down by the Police who showed us how to pay the toll and $2 dollar penalty, yes a $2 penalty for being in the wrong lane hardly seems worthwhile collecting it.
