You're right that's better, but it doesn't completely invalidate my prediction, it just means I might be out a bit with the time. Battery kWh / kg is also improving too, I just don't know if it's at the same rate as price. Its possible now with Teslas to buy the higher kWh batteries and they go further, so it's not like weight is the only factor. The new Tesla Roadster coming in 2020 [0] has a 620 mile range because it's basically a battery and little else. So it depends on: 1. how much the extra weight/drag of a model 3 chassis would reduce the range 2. how much of the $200,000 price is down to the battery. Then you are waiting until the price of the battery comes down. [0]: https://www.tesla.com/roadster https://www.tesla.com/roadster
