This needs to be consistent. I typed just the word Hamilton and it accepted it, then Bottas and it accepted it, then Verstappen, Alonso, Vettel, same. And then it didn't accept any other ones with just last names. I tried Norris, Russell, Stroll, Tsunoda, Perez, Sainz, Schumacher, Mazepin, Ricciardo before I gave up b/c I thought there was something wrong with the quiz. Turned out it stopped accepting last names.
