In vehicles, traditional Ethernet required point-to-point connections, which added switches and increased weight, complexity, and cost. To address power consumption, heat, and complexity, we switched to 10BASE-T1S, a simpler, more efficient Ethernet technology.

10BASE-T1S changes everything. It restores the simplicity of a bus topology, allowing multiple ECUs to share a single wire. Most ECU communication is under 10 Megabits per second, making 10BASE-T1S ideal for control data, just like CAN and FlexRay, but fully Ethernet. Today's cars use many network types, connected by complex gateways, but there's a movement toward a single unified network: Ethernet everywhere.
