70's technology ? You're kidding , right ? The Lithium battery of today is vastly different to the original invention.

There's no new battery tech commercially available but there is massive amounts of development under testing right now.

How do think Tesla can come up with the performance for his truck and roadster range without some significant battery/supercap development ?

Your right about Rivian's availability. Production starts in 2020 with them becoming available within 12 months of the start of production. So it will be 2021 rather than 2020. My bad.
