Listen any public consultation on how our cars should be secured is just asking for someone to crack it and then we are all at risk, as R31Nismoid said, the less people that know about how your car is hooked up, the better. Even us talking about what alarm system we are going to buy and discussing the ins and outs of each system here is a risk, but honestly if they really really really wanted the car it would take something unique to stop people who know what they are doing. Im not sure whats the go lately with cars being stolen such as being random events or calculated pre-planned theft but either way we have to remember this a public forum and anything we say can be used against us unfortunately.
