What are the drivers' last names and id who had 11 pit stops and participated in more than 5 race results?
SELECT T1.surname ,  T1.driverid FROM drivers AS T1 JOIN pitstops AS T2 ON T1.driverid  =  T2.driverid GROUP BY T1.driverid HAVING count(*)  =  11 INTERSECT SELECT T1.surname ,  T1.driverid FROM drivers AS T1 JOIN results AS T2 ON T1.driverid  =  T2.driverid GROUP BY T1.driverid HAVING count(*)  >  5
drivers' last names refers to surname; drivers' id refers to driverid; had 11 pit stops refers to COUNT(pitstops) = 11; participated in more than 5 race results refers to COUNT(results) > 5; INTERSECT is used to find drivers who meet both conditions.
