Freelander alarm system

Just had another bizarre occurrence happen with my hippo's alarm, first time woke up at around 1pm sounded like a taxi, people getting out etc; alarm went off, jumped/fell out of hammock, checked car, fine no dints. Second time it happened I a saw the taxi drive past and set the alarm off, and the third time tonight just now, same thing! Could this just be a coincidence or can a taxi radio frequency screw with the Freelander alarm system?

Cheers

Do you have anything dangling from the mirror, such as a CD or furry dice? Any vehicle going past can make the car rock and set things swinging which can set off the interior motion alarm.

I've got a rabbit's foot hanging on the rear view mirror, I'll take that off and see if it happens again, thanks.

Be unlucky if it was that !!!

Wasn't lucky for the rabbit.
