The fines for speeding obviously aren't as high for you as they are here in Australia. The likelihood of being caught is also quite high.
Our highest speed limit here is 110km/h on divided freeways. Driving at 160km/h (>45km/h over the limit) attacts a very high fine and immediate licence suspension. The suspension would most likely be 3-6 months although it can be longer if you have done it before.
Even exceeding the limit by smaller amounts attracts quite large fines and if you do it 2-3 times within a 3 year period you will lose your licence for 3 months.
The CX-9 is so easy to drive fast I wish mine DID have an overspeed indicator like my last car did.
An interesting aside .... just yesterday our State Govt announced trials of GPS enforced speed limits for cars. They are trialing a system where an onboard GPS knows the speed limit for the road you are on and warns you if you go over it. The system is also capable of slowing the vehicle down to the speed limit if that function is enabled. It is likely to be years before we see anything like that as standard but I actually think it is a good idea. Everybody travelling at a uniform speed would allow for much traffic better flow.
