I'm currently abroad driving a hired Astra which has a lane departure system which tries to take over the steering, but it does not give an audible warning. It is intermittent in operation because in order to function it has to see two white lines, one on each side. I think the C-RV has something similar, and it may well be fitted in the new hybrid Jazz. I think I prefer the current Jazz system with the audible warning for crossing a single line on either side without signalling, as per the training mantra "Mirror, Signal, Manoeuvre".
