I read an article that Teslas are designed to have thier electrics in a daisy chain to avoid big ugly bundles of wires. But that just means a failure propagates down the chain so non critical systems can take out critical ones. Clearly he doesn’t listen to or hire car engineers.
He’s getting flamed because convertibles have been doing frameless door windows forever with manual overrides. It’s not something super special Tesla has done. Musk just doesn’t want to spend the extra money doing it right.
