No such luck. iDrive showed my car at the bank changing direction but not moving the entire trip over. The little arrow didn't know what was going on. It moved with the boat but would not show me in/on the water. Then when I drove off the ferry it suddenly showed me on the other side. Interesting... I was hoping to see my car in the water though.

You must have been parked somewhere with a roof over your car. If the car can't see the satellites, it relies on dead reckoning and the electronic compass. It thought you were standing still (but the electronic compass noticed you were magically changing the direction you were facing, hence the arrow turning). Once it saw the sats, it knew where you were again.
