There has been concern that cyber criminals can hack into vehicles and take control while someone is driving,
but a more immediate problem is the theft of the vehicle itself. Hackers can now overcome the vehicle security systems by using hi-tech devices to intercept signals from key fobs and once into the vehicle they have similar devices to overcome the vehicle diagnostics and drive off.
Generally it is high value vehicles being targeted, although any vehicle is potentially at risk and victims may have to answer awkward questions from insurers as to whether the car was locked or not, particularly if it has just been broken into rather than stolen.
Security solutions such as those using the driver identity are available, but expensive and some fleet owners are turning to good old fashioned deadlocks to secure their vehicles.
