Adding the part outside of Corby ring to cruise area

[Marty_Deslions]

Okay very quick, today I was in a chase on Corby, and I drove into the tunnel that leads to the part that's just outside the ring. I got told by insim that I should return to cruise area, eventhough this is clearly also part of the cruise area, since it's normal road. I'm assuming this warning/autobust isn't done intentional at this area but maybe rather to prevent people from staying in chase when they are sent OOB or something. However I strongly feel this area here should also be added to the cruise area.
If not, then maybe block this whole area off so people don't go there accidentely during chase.

No poll, because this should be pretty obvious, and is more like a bug report.
