There might now be motivation to deliver fully electric brake systems. They would have to be very reliable. A path to there could first be a small hydraulic pump for every wheel. For AC and battery thermal management, having a fluid is more fundamental. Solid state heat engines have terrible efficiency currently. Bikes have started using hydraulic disc brakes instead of cables, even when self service is much harder. Going the other way.
