As well as the ability to activate brake locking while parked, maybe it would be useful to have some form of panic button which could be pressed in a hijack situation, which would use a hill start type mechanism to lock on the rear brake and would also disable the ignition, rendering the bike unusable to anyone, even the owner. I would suggest just the rear brake as this should be enough to stop the bike being pushed away. This would mean that even if thieves had gained possession of the key or keyless fob they would still be unable to unlock or start the bike. Of course this would be a bit of a problem for the owner too after a failed hijack attempt, but maybe there could be some sort of arrangement whereby the owner could be given a code on the dashboard after a delay of say 30 minutes, to provide to a helpdesk, and would in return be sent a PIN code to unlock the bike, subject to suitable arrangements to ensure that the owner was not requesting this under duress, though I would suggest that not many potential hijackers are going to want to hang around at the scene of such an incident for 30 minutes!
