I'd argue that chassis tech is more sophisticated in the BEV case due to more weight. Adaptive dampers, air springs, rear-axle steering, etc. might not be necessary on a comparably sized ICE vehicle. OTOH, ABS and ESP systems can achieve similar or even better results with less complexity because motor torque control is inherently low-latency, which can also complement brake deployment (hydraulics is not as well behaved as e-motor). You do get rid of emissions control and tiny little sensors / flap actuators sprinkled all around the engine bay, so yeah, probably overall still a simplification win, but I doubt you can get very far without "massive amounts of [Mechatronics] engineering".
