In terms of security measures, there is little Ms Megan Tay can do.

She left the most fundamental security measure exposed - her car keys were unattended on the table while she was at the dance floor.

The ease and the little amount of effort required to "usurp" her Maserati was probably too attractive for the car thief.
But there are also people on the other end of the spectrum. These people not only won't leave their car keys lying around, they will also take "extra steps" to reinforce the security of the car.
