From the Harman press release:

While it is worth verifying and contextualising the statistic quoted by Atzmon, automotive cyber security is indeed becoming an increasingly critical aspect of vehicle technology. This is especially evident in the wake of demonstrations highlighting the catastrophic impact that a cyber attack can have on a car's safety and mobility.
Perhaps the best example of this increasingly rapid and methodical computerisation of cars is Harman itself, which until recently was known almost exclusively as a manufacturer of high-end audio systems under brands such as Bowers & Wilkins, JBL, Harman/Kardon and Mark Levinson. I strongly suspect that the company's audio business will soon be displaced by, or at a minimum, be given equal importance to, the firm's cyber-security and other automotive technology businesses.
