I installed 8500 Panasonic 18650 cells in a 1970 VW driving it 235 miles before needing a recharge, this was before Tesla released the Roadster. Additionally I was a EV instructor in Fremont, CA. teaching EV conversion and Hybrid technology to laid off students from NUMI, later to be hired by Tesla using a Certificate of Completion I provided them at the end of the class. So, to be fair and set the record straight, the Tesla car was NOT the first electric car to be powered by Li-ion batteries, i.e. Panasonic 18650 cells.
