I, completely pulling this from thin air, would say no. When the inevitable error happens in a network setting, one error could effect every car that shared a given property (say, every car on the same road.) Or it could send a semi down a street the wrong way and not catch the error, taking out every other car coming in the opposite direction until the semi is pieces. Autonomously, with each car working for itself, the inevitable error could effect many cars, but, at least the other cars could potentially compensate by swerving. Similarly, I'd rather have a home server than have everything in the cloud.
