Table schema:
CREATE TABLE table_name_67 (rider VARCHAR, time VARCHAR, manufacturer VARCHAR, grid VARCHAR, laps VARCHAR)

Question: What is Rider, when Grid is less than 16, when Laps is 21, when Manufacturer is Honda, and when Time is +10.583?
SQL: SELECT rider FROM table_name_67 WHERE grid < 16 AND laps = 21 AND manufacturer = "honda" AND time = "+10.583"
