Cape Town - Security features in modern cars make it increasingly difficult for criminals to make off with them while they were parked, acting police commissioner Lieutenant-General Khomotso Phahlane said on Friday.
This partly explained a 14.3% increase in carjackings in the past year, even though there had been a decrease in vehicle theft, he told Parliament's police portfolio committee.
"It has become more difficult to break in and get the car started. The easier way is to get you out of your vehicle so you are able to hand over your keys."
Police were aware of the situation and trying to stop it with the help of other crime-fighting bodies.
In many instances, there was a market for certain cars, and orders were put in beforehand.
"We continue to do analysis to counter such," he said.
Carjacking was most prevalent in the heavily populated and economically active province of Gauteng.
