Who are all the drivers?
assistant
SELECT * FROM drivers;

Show the id and number of races of those who have at most participated in 30 races.
assistant
SELECT T1.driverid , COUNT( * ) FROM drivers AS T1 JOIN results AS T2 ON T1.driverid = T2.driverid JOIN races AS T3 ON T2.raceid = T3.raceid GROUP BY T1.driverid HAVING COUNT( * ) <= 30 ;
