From The Verege: "Vehicle crashes involving Level 2 systems that don’t involve a fatality or vulnerable road user are now exempted from reporting." Teslas are Level 2, thus exempt. Waymo are Level 4 and thus reporting is compulsory. Conclusions are left as an exercise for the reader.

It may not be a hub motor, but the planetary assembly is attached to the wheel, so it is unsprung. From their diagrams, it looks as though they still have a CV joint, but it only needs to accommodate angles for the steering of the wheel and not for suspension travel. So "less complicated" would not seem to be a good characterization. From the diagram it looks as though they are still using a Rzeppa joint to couple between a motor fixed on the chassis and the wheel. I would say that the argument about problems with unsprung weight apply. And he did not mention tire stress and wear as unsprung-weight problems.

Comment Ferguson Big Board (Score 1) 523

Ferguson Big Board, hand-built from a kit, with heavy-duty analog power supply, two SA800 floppies, Avdek monitor. Custom beechwood plywood enclosure lined with copper screen to cut down on EMI. Floppies were re-pulleyed 50Hz European-market drives. One failed immediately and was replaced with SA0801. I still have the hardware -- and the schematics.
