I agree with Richard. Just off the top of my head the research and costs for traction control which was never adopted on Aero series would be prohibitive. As suggested MMC's adoption of CANBUS system in general was flaky on the Aero series leading to all sorts of issues as is, indicators being one of them. Having said that I believe the later Aero S4 and onwards models featured ABS and EBD for brake system.
