  1. The Cybertruck is undoubtedly very efficient but you are overstating your case. HGV diesels can get close to 50% efficiency. Car diesels around 40%. Petrol at best is 30% more likely less than 20%. But batteries and motors are not around 90%. The power has to be generated and transmitted. The best gas fired plants are around 65% but there are losses in transmission of power and for pumping gas. So an electric truck or car is really getting 90% of 50%. About the same as HGV diesel. The big win is power recovered in braking and part load efficiency. The US EPA says a Tesla car has an MPG equivalent of 150mpg (UK gallon). At least three times that of a piston engine car. A Tesla truck will have the same tech so expect to see some stunning figures.

  2. Full Self Driving will arrive. When it does truck driving and taxi driving JOBS will be the first to go. Within 10 years people in towns will stop buying cars. Why bother when you can rent a Tesla for 5p a mile.
