Skyrocketing vehicle theft rates in some U.S. cities have drawn attention to an inconvenient truth: the increasing amount of technology in our vehicles can make them increasingly vulnerable to hacking or theft.
The best way to "foil car thieves" is to drive a junker vehicle. Nobody is going to waste their time and potential jail time stealing a car worth less than $1000 USD in parts, unless they really just want to fuck with you.
Also never drive a Hyundai. South Korean auto manufacturers are the absolute worst.
There is no evidence suggesting older vehicles are less likely to be stolen.
Junker vehicles may be more likely to be stolen because they are easier to steal. This is usually because they have less and/ or poor security features. Older vehicles can be favoured targets because their parts are more valuable due to their scarcity because they are out of production.
