You're cherry-picking data to make Tesla's numbers and potential look worse than they actually are.
The first two quarters are much slower for car sales; for example in 2020, Tesla shipped 178k units in Q1+Q2 and 319k units in Q3+Q4.
Tesla had sales of 31.5B in 2020, and have 73% growth between Q3 2020 and 2021, which indicates they could hit 50B in 2021, and could hit close to 90B in 2022 if they continue the same YoY growth. Nissan is stagnant. It's reasonable to assume that Tesla is on track to surpass Nissan next year (2022).
Tesla had automotive revenues of 19 billion usd in the first two quarters of 2021.
