He's talking about a drag strip. 15% faster on a race track would be mind blowingly good. To put it in perspective in this test a Ferrari 488 was only 18% faster than a Mazda Miata. Best Driver’s Lap: Slot Car Seca - Motor Trend
Also to keep it in perspective a Model S is slower than a stock Mazda Miata around Laguna Seca. Tesla has a long way to go before it can compete in that realm.
Ferrari 488 1:31.68
BMW M4 GTS 1:37.66
Mazda Miata 1:51.43
Model S (Refuel 2017) 1:52.43 (I'm guessing this was probably not on stock tires)
Interesting reading with a good comparison of different cars on the same track. Refuel 2017 was epic
