Table schema:
CREATE TABLE table_name_89 (grid VARCHAR, laps VARCHAR, time_retired VARCHAR, driver VARCHAR)

Question: How much Grid has a Time/Retired of +1 lap, and a Driver of sébastien bourdais, and Laps larger than 70?
SQL: SELECT COUNT(grid) FROM table_name_89 WHERE time_retired = "+1 lap" AND driver = "sébastien bourdais" AND laps > 70
