<human>: What are the best ways to protect my car against carjacking?
<bot>: The best way to protect your car from being carjacked is to park in a well-lit, busy area and avoid parking in isolated areas. Make sure all windows and doors are locked and that any valuables inside the vehicle are secured or out of sight. Consider installing anti-theft devices such as LoJack or OnStar. Additionally, if you have an alarm system installed, make sure it's activated before leaving the vehicle.
